WATCHDOG: sb_wdog: Fix 32 bit build failure
Fixes the following linking problem: drivers/watchdog/sb_wdog.c:211: undefined reference to `__udivdi3' This results from reading a 64 bit register, then dividing the value by 1000000. For 32 bit kernels gcc will use the helper function __udivdi3 from libgcc which the kernel intentionally doesn't provide. In the read registerbits 23..63 are always zero and only bits 0..22 are signficant. So a simple cast to truncate the read value to 32 bits fixes the issue. Reported and initial patch by Markos Chandras <markos.chandras@imgtec.com>. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Reported-by: Markos Chandras <markos.chandras@imgtec.com>
