2008-06-26V4L/DVB (8026): Avoids an OOPS if dev struct can't be successfully recoveredMauro Carvalho Chehab
On some alsa versions, it seems that snd_pcm_substream_chip(substream) is returning a NULL pointer. This causes an OOPS, as reported by: https://bugs.launchpad.net/ubuntu/+source/linux-ubuntu-modules-2.6.24/+bug/212271 https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/212960 This patch avoids the OOPS by not letting and open() succeed.

2008-06-05V4L/DVB (7974): fix MEDIA_TUNER && FW_LOADER build errorIngo Molnar
-tip testing found the following build failure: LD .tmp_vmlinux1 drivers/built-in.o: In function `generic_set_freq': tuner-xc2028.c:(.text+0xbd896): undefined reference to `request_firmware' tuner-xc2028.c:(.text+0xbdd7a): undefined reference to `release_firmware' drivers/built-in.o: In function `xc_load_fw_and_init_tuner': xc5000.c:(.text+0xc68e6): undefined reference to `request_firmware' xc5000.c:(.text+0xc6abe): undefined reference to `release_firmware' with this config: http://redhat.com/~mingo/misc/config-Tue_May_20_18_11_34_CEST_2008.bad the reason is another kconfig tool bug that has to be worked around in the driver's Kconfig file: if FW_LOADER is selected in a second dependency, that is not properly propagated up the dependencies. in this case, FW_LOADER is selected from MEDIA_TUNER_XC2028: config MEDIA_TUNER_XC2028 tristate "XCeive xc2028/xc3028 tuners" depends on VIDEO_MEDIA && I2C depends on HOTPLUG select FW_LOADER which got selected by MEDIA_TUNER: config MEDIA_TUNER tristate default VIDEO_MEDIA && I2C depends on VIDEO_MEDIA && I2C select FW_LOADER if !MEDIA_TUNER_CUSTOMIZE && HOTPLUG but the kconfig tool did not pick up this second-order dependency and allowed CONFIG_FW_LOADER=m to be selected - in which case the build fails. the workaround i found was to move the select of FW_LOADER one level up, so that the buggy kconfig tool can notice it and can act appropriately. This problem can probably be worked around in other ways as well, i went for the minimal fix. Obviously, the kconfig tool should be fixed, it is not reasonable to expect driver authors to do manual dependency resolution (that kconfig itself already does) and uglify the Kconfig files. The kconfig tool did nothing to warn about this situation and did not prevent this faulty .config from being constructed.
