[PATCH 5.15 278/846] um: fix ndelay/udelay defines
From: Greg Kroah-Hartman
Date: Mon Jan 24 2022 - 17:48:19 EST
From: Johannes Berg <johannes.berg@xxxxxxxxx>
[ Upstream commit 5f8539e2ff962e25b57742ca7106456403abbc94 ]
Many places in the kernel use 'udelay' as an identifier, and
are broken with the current "#define udelay um_udelay". Fix
this by adding an argument to the macro, and do the same to
'ndelay' as well, just in case.
Fixes: 0bc8fb4dda2b ("um: Implement ndelay/udelay in time-travel mode")
