[ Upstream commit 5b11c9d80bde81f6896cc85b23aeaa9502a704ed ]
An old cleanup changed the array size from MAX_ADDR_LEN to unspecified in the declaration, but now gcc-11 warns about this:
drivers/scsi/fcoe/fcoe_ctlr.c:1972:37: error: argument 1 of type ‘unsigned char[32]’ with mismatched bound [-Werror=array-parameter=] 1972 | u64 fcoe_wwn_from_mac(unsigned char mac[MAX_ADDR_LEN], | ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~ In file included from /git/arm-soc/drivers/scsi/fcoe/fcoe_ctlr.c:33: include/scsi/libfcoe.h:252:37: note: previously declared as ‘unsigned char[]’ 252 | u64 fcoe_wwn_from_mac(unsigned char mac[], unsigned int, unsigned int); | ~~~~~~~~~~~~~~^~~~~
Change the type back to what the function definition uses.
