From: Thomas Falcon Date: Fri, 7 Jun 2019 21:03:55 +0000 (-0500) Subject: ibmvnic: Fix unchecked return codes of memory allocations X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7c940b1a5291e5069d561f5b8f0e51db6b7a259a;p=openwrt%2Fstaging%2Fblogic.git ibmvnic: Fix unchecked return codes of memory allocations The return values for these memory allocations are unchecked, which may cause an oops if the driver does not handle them after a failure. Fix by checking the function's return code. Signed-off-by: Thomas Falcon Signed-off-by: David S.
