From: Raghava Aditya Renukunta Date: Thu, 16 Feb 2017 20:51:21 +0000 (-0800) Subject: scsi: aacraid: Reorder Adapter status check X-Git-Tag: v4.11-rc1~7^2~47 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=c421530bf848604e97d0785a03b3fe2c62775083;p=linux.git scsi: aacraid: Reorder Adapter status check The driver currently checks the SELF_TEST_FAILED first and then KERNEL_PANIC next. Under error conditions(boot code failure) both SELF_TEST_FAILED and KERNEL_PANIC can be set at the same time. The driver has the capability to reset the controller on an KERNEL_PANIC, but not on SELF_TEST_FAILED. Fixed by first checking KERNEL_PANIC and then the others.
