From 73029e0ff18dfac8a1aab1dc188e1e150bbe3adc Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 13 Apr 2010 11:39:47 +0200 Subject: 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.
