Subject: m32r: fix build warning
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=17e96230d95cc2b7eb7d039415d3506340257b5e;p=linux-beck.git

m32r: fix build warning

While building m32r defconfig we got warnings:

  arch/m32r/platforms/m32700ut/setup.c:249:24: warning: 'm32700ut_lcdpld_irq_type' defined but not used [-Wunused-variable]

m32700ut_lcdpld_irq_type is only used when CONFIG_USB is enabled.
Modify the code to declare the related variables and functions only when
CONFIG_USB is enabled.
