Subject: [PATCH] fixup! Allow mac address to be set in smsc95xx
|
|
|
|
usbnet: smsc95xx: Fix indentation of smsc95xx_is_macaddr_param()
|
|
|
|
smsc95xx_is_macaddr_param() is incorrectly indented, it uses 7 spaces
|
|
instead of tabs. Fix it.
|
|
|
|
Fixes: aac7b105788e ("Allow mac address to be set in smsc95xx")

usbnet: smsc95xx: Simplify MAC address parsing
|
|
|
|
Parsing the MAC address provided on the kernel command line can be
|
|
simplified quite a bit by taking advantage of the kernel's built-in
|
|
mac_pton() helper.
|
|
|
|
Likewise emitting the MAC address can be simplified with the %pM
|
|
format string conversion.

usbnet: smsc95xx: Fix style issues in smsc95xx_is_macaddr_param()
|
|
|
|
It is bad practice to have a function named ..._is_...() which has side
|
|
effects. So drop the 'is' from the name.
|
|
|
|
Per kernel convention return 0 on success and a negative errno on
|
|
failure.
|
|
|
|
Validate the MAC address retrieved from the command line.
