2019-07-26ALSA: i2c: ak4xxx-adda: Fix a possible null pointer dereference in build_adc_controls()Jia-Ju Bai1-3/+4
In build_adc_controls(), there is an if statement on line 773 to check whether ak->adc_info is NULL: if (! ak->adc_info || ! ak->adc_info[mixer_ch].switch_name) When ak->adc_info is NULL, it is used on line 792: knew.name = ak->adc_info[mixer_ch].selector_name; Thus, a possible null-pointer dereference may occur. To fix this bug, referring to lines 773 and 774, ak->adc_info and ak->adc_info[mixer_ch].selector_name are checked before being used. This bug is found by a static analysis tool STCheck written by us. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2018-08-03ALSA: i2c: Remove empty init and exitTakashi Iwai1-12/+0
For a sake of code simplification, remove the init and the exit entries that do nothing. Notes for readers: actually it's OK to remove *both* init and exit, but not OK to remove the exit entry. By removing only the exit while keeping init, the module becomes permanently loaded; i.e. you cannot unload it any longer! Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai1-1/+0
This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

2006-09-23[ALSA] ak4xxx - Remove bogus IPGA controlsTakashi Iwai1-110/+18
Remove IPGA volume controls and merge the IPGA range to ADC volume controls. These two volumes are not really independent but connected simply in different ranges 0-0x7f and 0x80-max. It doesn't make sense to provide two controls. Since both 0x7f and 0x80 specify 0dB, a hack is needed for IPGA range to skip 0x80 (increment one) for such controls.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+501
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!
