Subject: [PATCH] sound: Fix warnings relating to ignored return value in
snd_card_register
Do not ignore the return of 'device_create_file' in
'snd_card_register' and thereby fixing the following warnings:
sound/core/init.c: In function 'snd_card_register':
sound/core/init.c:640: warning: ignoring return value of
'device_create_file', declared with attribute warn_unused_result
sound/core/init.c:641: warning: ignoring return value of
'device_create_file', declared with attribute warn_unused_result
