Subject: OMAP1/2/3 clock: remove paranoid checks in preparation for clock{,2xxx,3xxx}_data.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ebd893ded2733b8bd9ba403ee4a9e6ab6fbc2a54;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

OMAP1/2/3 clock: remove paranoid checks in preparation for clock{,2xxx,3xxx}_data.c

Some parts of the clock code took advantage of the fact that the statically
allocated clock tree was in clock{,24xx,34xx}.c's local namespace to do some
extra argument checks.  These are overzealous and are more difficult to
maintain when the clock tree is in a separate namespace, so, remove them.
