commit 3f5f7335e5e234e340b48ecb24c2aba98a61f934 upstream.

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.

Fixes: 9c2b297572bf ("[SCSI] qla2xxx: Support for loading Unified ROM Image (URI) format firmware file.")
