Subject: [PATCH 3/3] ata: simplify clock divisor logic in pata_amd.c
Current code is essentially choosing between dividing by 1 or
dividing by two, make the conditions a little more obvious.
As a bonus, removes a sparse error:
drivers/ata/pata_amd.c:59:11: warning: symbol '__x' shadows an earlier one
drivers/ata/pata_amd.c:59:11: originally declared here
Signed-off-by: Harvey Harrison <harvey.harrison@xxxxxxxxx>

Thought I'd follow up with just what the 3/3 patch I referenced was.
