x86/platform/intel-mid: Make several arrays static, to make code smaller
Don't populate arrays on the stack, instead make them static. Makes the object code smaller by 76 bytes: Before: text data bss dec hex filename 4217 1540 128 5885 16fd arch/x86/platform/intel-mid/pwr.o After: text data bss dec hex filename 3981 1700 128 5809 16b1 arch/x86/platform/intel-mid/pwr.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Cc: Bjorn Helgaas <bhelgaas@google.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Lukas Wunner <lukas@wunner.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: kernel-janitors@vger.kernel.org Link: http://lkml.kernel.org/r/20170825163206.23250-1-colin.king@canonical.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
