Subject: [PATCH] iio: accel: st_accel: Mark default_accel_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 default_accel_pdata with __maybe_unused to calm a compiler down:
In file included from drivers/iio/accel/st_accel_i2c.c:19:
drivers/iio/accel/st_accel.h:67:46: warning: ‘default_accel_pdata’ defined but not used [-Wunused-const-variable=]
67 | static const struct st_sensors_platform_data default_accel_pdata = {
| ^~~~~~~~~~~~~~~~~~~
