Subject: [PATCH v3 1/5] wifi: rtl8xxxu: Deduplicate the efuse dumping code
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit
Precedence: bulk

Every chip family except RTL8723AU has a copy of the efuse dumping
code. Remove this and dump the efuse from a single place using a new
function rtl8xxxu_dump_efuse().

Also, use print_hex_dump() to print the efuse instead of a loop and
dev_info(). It shows the ASCII interpretation of the bytes, which is
nice.

v3:
 - Implement suggestion from Ping-Ke Shih:
   - Use EFUSE_MAP_LEN instead of EFUSE_REAL_CONTENT_LEN_8723A.
     They have the same value.

v2:
 - Patch is new in v2.
