Subject: RAS: ras_common: Add null pointer check for error record probe function
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=4576f73caa99c95029b3abe0c2893b83d635ebf6;p=project%2Fbcm63xx%2Fatf.git

RAS: ras_common: Add null pointer check for error record probe function

Add a null pointer check for the error record probe
function -- avoids a panic in case a platform has not defined it.
