#1228386 — [PATCH] nios2: Fix unused variable warning

FromMarek Vasut <marex@denx.de>
Date2015-09-19 06:50 +0200
Subject[PATCH] nios2: Fix unused variable warning
Message-ID<qaig2-7KZ-7@gated-at.bofh.it>
Fix the following compiler splat by adding __maybe_unused annotation
to the variable. Using this particular annotation has the least ugly
impact on the code compared to using ifdeffery.

arch/nios2/kernel/setup.c: In function 'nios2_boot_init':
arch/nios2/kernel/setup.c:107:7: warning: unused variable 'cmdline_passed' [-Wunused-variable]
  char cmdline_passed[COMMAND_LINE_SIZE] = { 0, };
       ^
