Subject: [PATCH] iio: accel: Replace zero-length arrays with DECLARE_FLEX_ARRAY() helper
Date: Sun, 30 Jul 2023 18:44:06 -0700 [thread overview]
Message-ID: <20230731014406.22810-1-rauji.raut@gmail.com> (raw)
Replacing zero-length arrays with C99 flexible-array
members since they are obsolete.
Use the new DECLARE_FLEX_ARRAY() auxiliary macro instead
of defining a zero-length array.
This fixes warnings such as:
./drivers/iio/accel/adxl367_spi.c:38:6-17: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
