These are caused by the 900-mdio_bitbang_ignore_ta_value and
901-phy-mdio-bitbang-prevent-rescheduling-during-command patches.
The first patch removes some code but it does not remove the variable
which is used by the removed code only.
The second patch adds local_irq_{save,restore} calls. The type of the
argument of these calls must be 'unsigned long', but the patch defines
the variable as 'long'.
Fix both patches to silence the warnings.
