Subject: SMC91x: Fix compilation on some platforms.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=55c8eb6c8eaa5009eed1557b296da5d4ea9c369a;p=linux-beck.git

SMC91x: Fix compilation on some platforms.

This reverts 51ac3beffd4afaea4350526cf01fe74aaff25eff ('SMC91x: delete
unused local variable "lp"') and adds __maybe_unused markers to these
(potentially) unused variables.

The issue is that in some configurations SMC_IO_SHIFT evaluates
to '(lp->io_shift)', but in some others it's plain '0'.

Based upon a build failure report from Manuel Lauss.
