Subject: OMAP4: clock: fix compile warning
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=450a37d2eca6ddf6ea8186f57a7531318df6e796;p=deliverable%2Flinux.git

OMAP4: clock: fix compile warning

Fix the following compile warning:

arch/arm/mach-omap2/clock44xx_data.c: In function 'omap4xxx_clk_init':
arch/arm/mach-omap2/clock44xx_data.c:3371:6: warning: 'cpu_clkflg' may be used uninitialized in this function

The approach taken here is intended to work if omap4xxx_clk_init() is
converted into an initcall.

Thanks to Bjarne Steinsbo <bsteinsbo@gmail.com> for proposing another
approach.
