Subject: scsi: fcoe: Fix mismatched fcoe_wwn_from_mac declaration
MIME-Version: 1.0

Git-commit: 5b11c9d80bde81f6896cc85b23aeaa9502a704ed
Patch-mainline: v5.13-rc1
References: bsc#1186528
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.
