Subject: [PATCH] soc: ti: pruss: Remove wrong check against *get_match_data return value
Date: Mon, 26 Oct 2020 15:49:43 +0100
Message-ID: <20201026144943.30821-1-grzegorz.jaszczyk@linaro.org> (raw)

Since the of_device_get_match_data() doesn't return error code, remove
wrong IS_ERR test. Proper check against NULL pointer is already done
later before usage: if (data && data->...).

Additionally, proceeding with empty device data is valid (e.g. in case
of "ti,am3356-pruss").
