| Subject: iio: adc: max9611: explicitly cast gain_selectors |
| |
| From: Stefan Agner <stefan@agner.ch> |
| |
| [ Upstream commit b1ec0802503820ccbc894aadfd2a44da20232f5e ] |
| |
| After finding a reasonable gain, the function converts the configured |
| gain to a gain configuration option selector enum max9611_csa_gain. |
| Make the conversion clearly visible by using an explicit cast. This |
| also avoids a warning seen with clang: |
| drivers/iio/adc/max9611.c:292:16: warning: implicit conversion from |
| enumeration type 'enum max9611_conf_ids' to different enumeration |
| type 'enum max9611_csa_gain' [-Wenum-conversion] |
| *csa_gain = gain_selectors[i]; |
