ALSA: info - Implement common llseek for binary mode
The llseek implementation is identical for existing driver implementations, so let's merge to the common layer. The same code for the text proc file can be used even for the binary proc file. The driver can provide its own llseek method if needed. Then the common code will be skipped. Signed-off-by: Takashi Iwai <tiwai@suse.de>
