Subject: [PATCH] qla2xxx: Fix the endianness of the qla82xx_get_fw_size() return type
Date: Wed, 18 Dec 2019 16:49:05 -0800
Message-ID: <20191219004905.39586-1-bvanassche@acm.org> (raw)

Since qla82xx_get_fw_size() returns a number in CPU-endian format, change
its return type from __le32 into u32. This patch does not change any
functionality.
