Subject: um: fix ndelay/udelay defines
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2a2f4f3aeafd684d1f8d790ef1ccb663ec8eb844;p=linux.git

um: fix ndelay/udelay defines

[ 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.
