2012-08-14[media] move the dvb/frontends to drivers/media/dvb-frontendsMauro Carvalho Chehab
Raise the DVB frontends one level up, as the intention is to remove the drivers/media/dvb directory. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-07-31[media] dib8000: move dereference after check for NULLDan Carpenter
My static checker complains that we dereference "state" inside the call to fft_to_mode() before checking for NULL. The comments say that it is possible for "state" to be NULL so I have moved the dereference after the check.

2012-01-04[media] dvb: Remove ops->info.type from frontendsMauro Carvalho Chehab
Now that this field is deprecated, and core generates it for DVBv3 calls, remove it from the drivers. It also adds .delsys on the few drivers where this were missed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-12-31[media] dvb: don't require a parameter for get_frontendMauro Carvalho Chehab
Just like set_frontend, use the dvb cache properties for get_frontend. This is more consistent, as both functions are now symetric. Also, at the places get_frontend is called, it makes sense to update the cache. Most of this patch were generated by this small perl script: while (<>) { $file .= $_; } if ($file =~ m/\.get_frontend\s*=\s*([\d\w_]+)/) { my $get = $1; $file =~ s/($get)(\s*\([^\,\)]+)\,\s*struct\s+dtv_frontend_properties\s*\*\s*([_\d\w]+)\)\s*\{/\1\2)\n{\n\tstruct dtv_frontend_properties *\3 = &fe->dtv_property_cache;/g; } print $file; Of course, the changes at dvb_frontend.[ch] were made by hand, as well as the changes on a few other places, where get_frontend() is called internally inside the driver. On some places, get_frontend() were just a void function. Those occurrences were removed, as the DVB core handles such cases. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-12-31[media] dib8000: Remove the old DVBv3 struct from it and add delsysMauro Carvalho Chehab
This driver only uses the DVBv5 struct. All it needs is to remove the non-used params var, and to add the ISDB-T to the delivery systems. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-12-31[media] dvb-core: add support for a DVBv5 get_frontend() callbackMauro Carvalho Chehab
Creates a DVBv5 get_frontend call, renaming the DVBv3 one to get_frontend_legacy(), while not all frontends are converted. After the conversion for all drivers, get_frontend_legacy() will be removed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-12-31[media] Rename set_frontend fops to set_frontend_legacyMauro Carvalho Chehab
Passing DVBv3 parameters to set_frontend is not fun, as the core doesn't have any way to know if the driver is using the v3 or v5 parameters. So, rename the callback and add a new one to allow distinguish between a mixed v3/v5 paramenter call from a pure v5 call. After having all frontends to use the new way, the legacy call can be removed. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-12-31[media] tuners: remove dvb_frontend_parameters from set_params()Mauro Carvalho Chehab
This is a big patch, yet trivial: now that all tuners use the DVBv5 way to pass parameters (e. g. via fe->dtv_property_cache), the extra parameter can be removed from set_params() call. After this change, very few DVBv3 specific stuff are left at the tuners. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

This patch protects the I2C buffer access in order to manage concurrent access. This protection is done using mutex. Furthermore, for the dib9000, if a pid filtering command is received during the tuning, this pid filtering command is delayed to avoid any concurrent access issue.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
