Subject: [KJ] [PATCH] drivers/acpi: sizeof/sizeof array size calculations
Date: Sat, 26 May 2007 10:39:27 +0000	[thread overview]
Message-ID: <200705261239.27485.lists-receive@programmierforen.de> (raw)

This patch replaces lines in the acpi subsystem that use
sizeof/sizeof to determine the size of an array with the
ARRAY_SIZE(x) macro.

Signed-off-by: Andi Drebes <lists-receive@programmierforen.de>
