Subject: powerpc/mpic: Don't init the fsl error int until after mpic init
X-Git-Tag: firefly_0821_release~176^2~3789^2~30^2~4
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=aa80581da1448e9fe5ef3d1e56a82bbb21912ee1;p=firefly-linux-kernel-4.4.55.git
powerpc/mpic: Don't init the fsl error int until after mpic init
Besides other potential problems, if MPIC_NO_RESET is not set,
the error interrupt will be masked after it is requested.
