Subject: [PATCH] scsi: aacraid: fix a signedness bug
Git-commit: b9eb3b14f1dbf16bf27b6c1ffe6b8c00ec945c9b
Patch-Mainline: v4.19-rc3
References: bsc#1174296

The problem is that ->reset_state is a u8 but it can be set to -1 or -2 in
aac_tmf_callback() and the error handling in aac_eh_target_reset() relies
on it to be signed.

[mkp: fixed typo]
