Subject: [PATCH v4 01/21] nvmem: Mark nvmem_type_str array with __maybe_unused
Date: Wed, 28 Nov 2018 21:05:17 +0200	[thread overview]
Message-ID: <20181128190537.14074-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20181128190537.14074-1-andriy.shevchenko@linux.intel.com>

Since we put static variable to a header file it's copied to each module
that includes the header. But not all of them are actually using it.

Mark nvmem_type_str array with __maybe_unused to make a compiler happy:

In file included from include/linux/rtc.h:18,
                 from drivers/rtc/rtc-proc.c:15:
include/linux/nvmem-provider.h:29:27: warning: ‘nvmem_type_str’ defined but not used [-Wunused-const-variable=]
 static const char * const nvmem_type_str[] = {
                           ^~~~~~~~~~~~~~
