5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit bbc404d20d1b46d89b461918bc44587620eda200 ]
All error handling paths, except this one, go to 'out' where
release_swfw_sync() is called.
This call balances the acquire_swfw_sync() call done at the beginning of
the function.
Branch to the error handling path in order to correctly release some
resources in case of error.
Fixes: ae14a1d8e104 ("ixgbe: Fix IOSF SB access issues")
