[PATCH] thermal/core: avoid memory leak

From: Muhammad Usama Anjum
Date: Mon Mar 22 2021 - 15:12:53 EST


When memory allocation for cdev is successful but ida_simple_get fails,
branch to out_kfree_cdev label happens and cdev isn't freed. There are
other some other branches in which the memory can leaked. Fix it by
freeing cdev.
