Subject: [PATCH] ARM: footbridge rtc init
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=336eb02b9171d132a9abe575317fee4cca965af4;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[PATCH] ARM: footbridge rtc init

The footbridge ISA RTC was being initialised before we had setup the
kernel timer.  This caused a divide by zero error when the current
time of day is set.  Resolve this by initialising the RTC after
the kernel timer has been initialised.
