Compiling kernel 2.6.23 for an ARM/ixp4xx machine results in: arch/arm/mach-ixp4xx/common.c: In function 'ixp4xx_set_mode': arch/arm/mach-ixp4xx/common.c:445: warning: 'opts' may be used uninitialized in this function
The warning is valid: if ixp4xx_set_mode() is called with mode CLOCK_EVT_MODE_RESUME, then 'opts' will be uninitialised at the '*IXP4XX_OSRT1 = osrt | opts;' statement. Initialising opts to zero in this case may not be correct, but at least it's better than writing random junk to the hardware.
