Subject: [PATCH AUTOSEL 5.7 16/61] staging: rts5208: fix memleaks on error handling paths in probe

From: Evgeny Novikov <novikov@...ras.ru>

[ Upstream commit 11507bf9a8832741db69efd32bf09a2ab26426bf ]

rtsx_probe() allocates host, but does not free it on error handling
paths. The patch adds missed scsi_host_put().

Found by Linux Driver Verification project (linuxtesting.org).
