Subject: [PATCH] iio: gyro: st_gyro: Mark gyro_pdata with __maybe_unused
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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 used it.
Mark gyro_pdata with __maybe_unused to calm a compiler down:
In file included from drivers/iio/gyro/st_gyro_i2c.c:18:
drivers/iio/gyro/st_gyro.h:31:46: warning: ‘gyro_pdata’ defined but not used [-Wunused-const-variable=]
31 | static const struct st_sensors_platform_data gyro_pdata = {
| ^~~~~~~~~~
