[PATCH v2] scsi: qla2xxx: Simplify conditional check again

From: Nathan Chancellor
Date: Tue Mar 26 2019 - 18:06:45 EST

Clang warns when it sees a logical not on the left side of a
conditional statement because it thinks the logical not should
be applied to the whole statement, not just the left side:

drivers/scsi/qla2xxx/qla_nx.c:3703:7: warning: logical not is only
applied to the left hand side of this comparison

This particular instance was already fixed by commit 0bfe7d3cae58 ("scsi:
qla2xxx: Simplify conditional check") upstream but it was reintroduced
by commit 3695310e37b4 ("scsi: qla2xxx: Update flash read/write
routine") in the 5.2/scsi-queue.

Fixes: 3695310e37b4 ("scsi: qla2xxx: Update flash read/write routine")
Link: https://github.com/ClangBuiltLinux/linux/issues/80
Signed-off-by: Nathan Chancellor <natechancellor@xxxxxxxxx>

v1 -> v2:

* Reword commit message so make it clear this is just a reapplication of
a commit that is already in mainline, as suggested by Nick.

* Include the authors who reintroduced this warning.
