Subject: [PATCH v3] fix qla2xxx regression on sparc64
Date: Thu, 27 Aug 2020 22:27:29 +0200 (CEST)	[thread overview]
Message-ID: <20200827.222729.1875148247374704975.rene@exactcode.com> (raw)

Commit 98aee70d19a7e3203649fa2078464e4f402a0ad8 in 2014 broke qla2xxx
on sparc64, e.g. as in the Sun Blade 1000 / 2000. Unbreak by partial
revert to fix endianess in nvram firmware default initialization. Also
mark the second frame_payload_size in nvram_t __le16 to avoid new
sparse warnings.

Fixes: 98aee70d19a7e ("qla2xxx: Add endianizer to max_payload_size modifier.")
