From: Tobias Klauser Date: Mon, 27 Mar 2006 09:17:39 +0000 (-0800) Subject: [PATCH] drivers/video: Use ARRAY_SIZE macro X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d1ae418eef4ce763a95edec0b5fc095af5daca2e;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git [PATCH] drivers/video: Use ARRAY_SIZE macro Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove duplicates of ARRAY_SIZE. Some coding style and trailing whitespaces are also fixed. Compile-tested where possible (some are other arch or BROKEN) Signed-off-by: Tobias Klauser Cc: "Antonino A.
