[PATCH net-next 03/15] net: phy: aquantia: reorder AQR113C PMD Global Transmit Disable bit clearing with supported_interfaces
Posted by Vladimir Oltean 1 month, 1 week ago
Introduced in commit bed90b06b681 ("net: phy: aquantia: clear PMD Global
Transmit Disable bit during init"), the clearing of MDIO_PMA_TXDIS plus
the call to aqr107_wait_processor_intensive_op() are only by chance
placed between aqr107_config_init() and aqr107_fill_interface_modes().
In other words, aqr107_fill_interface_modes() does not depend in any way
on these 2 operations.

I am only 90% sure of that, and I intend to move aqr107_fill_interface_modes()
to be a part of aqr107_config_init() in the future. So to isolate the
issue for blame attribution purposes, make these 2 functions adjacent to
each other again.
