brcmsmac: make array addr static const, makes object smaller

2021-08-21T19:20:17Z

Don't populate the array addr on the stack but instead it static const. Makes the object code smaller by 79 bytes: Before: text data bss dec hex filename 176015 54652 128 230795 3858b .../broadcom/brcm80211/brcmsmac/main.o After: text data bss dec hex filename 175872 54716 128 230716 3853c .../broadcom/brcm80211/brcmsmac/main.o (gcc version 10.3.0) Signed-off-by: Colin Ian King Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20210819125552.8888-1-colin.king@canonical.com

brcmsmac: improve readability on addresses copy

2021-06-15T10:40:15Z

A static analyzer identified as a potential bug the copy of 12 bytes from a 6 bytes array to a 6 bytes array. Both arrays are 6 bytes addresses. Although not being a real bug, it is not immediately clear why is done this way: next 6 bytes address, contiguous to the first one, must also be copied to next contiguous 6 bytes address of the destination. Copying each one separately will make both static analyzers and reviewers happier.
