X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ff33f1821259d00d3fd85d86f59783e2ca3c9ee1;p=openwrt%2Fstaging%2Fblogic.git

fsl_rio: fix compile errors

Fixes the following compile problem on E500 platforms:
arch/powerpc/sysdev/fsl_rio.c: In function 'fsl_rio_mcheck_exception':
arch/powerpc/sysdev/fsl_rio.c:248: error: 'MCSR_MASK' undeclared (first use in this function)

Also fixes the compile problem on non-E500 platforms.
