Subject: MIPS: BCM63XX: allow NULL clock for clk_get_rate
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fa380301cdd54070bae40b00c8d06cf6fa35eeef;p=pandora-kernel.git

MIPS: BCM63XX: allow NULL clock for clk_get_rate

commit 1b495faec231980b6c719994b24044ccc04ae06c upstream.

Make the behaviour of clk_get_rate consistent with common clk's
clk_get_rate by accepting NULL clocks as parameter. Some device
drivers rely on this, and will cause an OOPS otherwise.
