X-Git-Tag: v2.6.12-rc3~27^2~14^2~4
X-Git-Url: http://git.samba.org/samba.git/?p=sfrench%2Fcifs-2.6.git;a=commitdiff_plain;h=336eb02b9171d132a9abe575317fee4cca965af4;hp=a757e64cfa400391041ed7953f0290c34a820c93

[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.
