Subject: sh: fix sh7723 SDHI support using INTC force_disable
X-Git-Tag: v2.6.34-rc1~285^2~18
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=838a4a9dcee0cbaeb0943531da00ac44d578f315;p=platform%2Fkernel%2Flinux-3.10.git

sh: fix sh7723 SDHI support using INTC force_disable

Update the sh7723 INTC tables with force_enable support
to mask out pending unsupported SDHI interrupt sources.

Without this patch the kernel locks up due to a pending
SDHI interrupt that the tmio_mmc driver cannot handle.
