6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Svyatoslav Pankratov <svyatoslav.pankratov@xxxxxxxxx>
[ Upstream commit 01aed663e6c421aeafc9c330bda630976b50a764 ]
There is no need to free the reset_data structure if the recovery is
unsuccessful and the reset is synchronous. The function
adf_dev_aer_schedule_reset() handles the cleanup properly. Only
asynchronous resets require such structure to be freed inside the reset
worker.
