2009-01-07i2c: Use snprintf to set adapter namesJean Delvare
Use snprintf instead of sprintf to set adapter names, it's safer. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-08-10i2c: Fix oops on bus multiplexer driver loadingJean Delvare
The two I2C bus multiplexer drivers (i2c-amd756-s4882 and i2c-nforce2-s4985) make use of the bus they want to multiplex before checking if it is really present. Swap the instructions to test for presence first. This fixes a oops reported by Ingo Molnar. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Ingo Molnar <mingo@elte.hu>
2008-07-16i2c: Clear i2c_adapter.dev on adapter removalJean Delvare
Clear i2c_adapter.dev on adapter removal. This makes it possible to re-add the adapter at a later point, which some drivers (i2c-amd756-s4882, i2c-nforce2-s4985) actually do. This fixes a bug reported by John Stultz here: http://lkml.org/lkml/2008/7/15/720 and by Ingo Molar there: http://lkml.org/lkml/2008/7/16/78 Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: John Stultz <johnstul@us.ibm.com> Cc: Ingo Molnar <mingo@elte.hu>
2008-07-14i2c: Bus drivers return -Errno not -1David Brownell
Tighten error paths used by various i2c adapters (mostly x86) so they return real fault/errno codes instead of a "-1" (which is most often interpreted as "-EPERM"). Build tested, with eyeball review. One minor initial goal is to have adapters consistently return the code "-ENXIO" when addressing a device doesn't get an ACK response, at least in the probe paths where they are already good at stifling related logspam.

2008-04-29i2c-amd756-s4882: Fix an error pathJean Delvare
If initialization fails, we want to restore the physical bus, not delete it again. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-02-13i2c: Declare more i2c_adapter parent devicesJean Delvare
Declare the parent device of i2c_adapter devices each time we can easily do so. It makes the i2c_adapter appear at the right place in the device tree, rather than as a platform device.

2006-03-23[PATCH] I2C: i2c-amd756-s4882: Improve static mutex initializationJean Delvare
Static mutexes can be initialized at declaration time. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-03-23[PATCH] i2c: Semaphore to mutex conversions, part 2Ingo Molnar
semaphore to mutex conversion. the conversion was generated via scripts, and the result was validated automatically via a script as well. build tested. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-11-07[PATCH] kfree cleanup: misc remaining driversJesper Juhl
This is the remaining misc drivers/ part of the big kfree cleanup patch. Remove pointless checks for NULL prior to calling kfree() in misc files in drivers/.

2005-10-28[PATCH] i2c: kzalloc cleanups, 2 of 2Jean Delvare
Use kzalloc instead of kmalloc in the S4882 SMBus multiplexing driver. I guess it's safer that way. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
