[PATCH] staging: r8188eu: use GFP_ATOMIC under spinlock
From: Michael Straube
Date: Mon Nov 08 2021 - 05:55:57 EST
In function rtw_report_sec_ie() kzalloc() is called under a spinlock,
so the allocation have to be atomic.
Call tree:
-> rtw_select_and_join_from_scanned_queue() <- takes a spinlock
-> rtw_joinbss_cmd()
-> rtw_restruct_sec_ie()
-> rtw_report_sec_ie()
Fixes: 2b42bd58b321 ("staging: r8188eu: introduce new os_dep dir for RTL8188eu driver")
