[16/16] net/bnxt: fix a possible memory leak
Checks
Commit Message
From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
During hot fw upgrade or error recovery, driver does cleanup and
reallocation of resources. But driver reallocates memory for ring
group info table without freeing the allocated memory during
device init.
Fix this memory leak by moving the freeing of ring group info table
to bnxt_free_mem() in bnxt_uninit_resources().
Fixes: 4617e2125c7f ("net/bnxt: refactor init and uninit functions")
