[PATCH V1] mfd: da9053: fix compiler warning message for uninitialised variable

Show all headers | View raw

From: Steve Twiss <stwiss.opensource@diasemi.com>

Fix compiler warning caused by an uninitialised variable inside
da9052_group_write() function. Defaulting the value to zero covers
the trivial case.

Hi Lee,

This compiler warning was found and reported by Geert Uytterhoeven as
part of the "Build regressions/improvements in v4.7-rc5" thread.

Regards,
Steve
