| |
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 8bb0a88600f0267cfcc245d34f8c4abe8c282713 ]
In the case where eq->fw->size > PAGE_SIZE the error return rc is being set to EINVAL however this is being overwritten to rc = req->fw->size because the error exit path via label 'out' is not being taken. Fix this by adding the jump to the error exit path 'out'.
