2018-08-08ALSA: opl3: Mark expected switch fall-throughGustavo A. R. Silva
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Addresses-Coverity-ID: 114878 ("Missing break in switch") Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-07-26ALSA: opl3: Declare common variables properlyTakashi Iwai
Move the declarations of common variables into opl3_voice.h instead of declaring at each file multiple times, which was error-prone. This fixes sparse warnings like: sound/drivers/opl3/opl3_synth.c:51:6: warning: symbol 'snd_opl3_regmap' was not declared. Should it be static? Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-07-16ALSA: opl3: remove redundant pointer opl3Colin Ian King
Variable opl3 is being assigned but is never used hence it is redundant and can be removed. Cleans up several clang warnings: warning: variable 'opl3' set but not used [-Wunused-but-set-variable] Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-10-24ALSA: drivers: Convert timers to use timer_setup()Kees Cook
In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2017-08-31ALSA: opl3: Put missing KERN_CONT prefixTakashi Iwai
The opl3 driver has a debug printk code without proper KERN_ prefix. On recent kernels, KERN_CONT prefix is mandatory for continued output lines. Put it properly. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-03-06ALSA: opl3: small array underflowDan Carpenter
There is a missing lower bound check on "pitchbend" so it means we can read up to 6 elements before the start of the opl3_note_table[] array. Thanks to Clemens Ladisch for his help with this patch. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-12-19ALSA: module_param: make bool parameters really boolRusty Russell
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Takashi Iwai <tiwai@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!
