[PATCH 5.13 171/175] net/qla3xxx: fix schedule while atomic in ql_wait_for_drvr_lock and ql_adapter_reset
From: Greg Kroah-Hartman
Date: Tue Aug 10 2021 - 14:07:53 EST
From: Letu Ren <fantasquex@xxxxxxxxx>
[ Upstream commit 92766c4628ea349c8ddab0cd7bd0488f36e5c4ce ]
When calling the 'ql_wait_for_drvr_lock' and 'ql_adapter_reset', the driver
has already acquired the spin lock, so the driver should not call 'ssleep'
in atomic context.
This bug can be fixed by using 'mdelay' instead of 'ssleep'.
