The patch titled
ps3av: misc updates
has been removed from the -mm tree. Its filename was
ps3av-misc-updates.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ps3av: misc updates
From: Geert Uytterhoeven <Geert.Uytterhoeven@xxxxxxxxxxx>
ps3av:
- Move the definition of struct ps3av to ps3av.c, as it's used locally only.
- Kill ps3av.sem, use the existing ps3av.mutex instead.
- Make the 512-byte buffer in ps3av_do_pkt() static to reduce stack usage.
Its use is protected by a semaphore anyway.
