Initializing the static variable to 0 causes the following error
when exec checkpatch:
ERROR: do not initialise statics to 0
FILE: sound/sound_core.c:142:
static int preclaim_oss = 0;
In addition, considering the following way of writing
139: #ifdef config_sound_oss_core_preclaim
140: Static int preclaim_oss = 1;
141: #ELSE
142: Static int preclaim_oss = 0;
143: #ENDIF
We can optimize it by IS_ENABLED(CONFIG_SOUND_OSS_CORE_PRECLAIM),
so modified it to
static int preclaim_oss = IS_ENABLED(CONFIG_SOUND_OSS_CORE_PRECLAIM);

Return the result from file->f_op->open() directly instead of
taking this in another redundant variable. Make the typical
return the last statement, return early and reduce the indentation
too.

Hi Meng Tang.
For the next time: it's not necessary (or even good) to add a sign-off
for another person unless they specifically authorize one.
You wrote and are submitting these changes, I merely gave you simple
suggestions as to how you could improve them.
cheers, Joe

Joe, would you like to drop your S-o-b lines from those two patches?
Or shall I keep them?
thanks,

Hi Takashi.
Nominally, the sign-off-by chain shows who pushed these changes upstream
and I did not and I am not an upstream aggregator.
But whatever you choose is OK.
It's not really a concern to me.
I do think these changes are ok.
cheers, Joe
