Merge branch 'net-phylink-phylink_resolve-cleanups'
Russell King says: ==================== net: phylink: phylink_resolve() cleanups This series does a bit of clean-up in phylink_resolve() to make the code a little easier to follow. Patch 1 moves the manual flow control setting in two of the switch cases to after the switch(). Patch 2 changes the MLO_AN_FIXED case to be a simple if() statement, reducing its indentation. Patch 3 changes the MLO_AN_PHY case to also be a simple if() statment, also reducing its indentation. Patch 4 does the same for the last case. Patch 5 reformats the code and comments for the reduced indentation, making it easier to read. ==================== Link: https://patch.msgid.link/Zy411lVWe2SikuOs@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>
