6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx> [ Upstream commit 1315848f1f8a0100cb6f8a7187bc320c5d98947f ] The kfree() function was called in one case by the get_filename() function during error handling even if the passed variable contained a null pointer. This issue was detected by using the Coccinelle software. Thus return directly after a call of the function “kzalloc” failed at the beginning.
