Subject: [PATCH v3 0/3] gpio: Simplify with device_get_match_data()

Changes in v3:
- Fix subjects and commit msg -> device_get_match_data
- Patch #3: Use dev_err_probe
- Link to v2: https://patch.msgid.link/20251219-gpio-of-match-v2-0-5c65cbb513ac@oss.qualcomm.com

Changes in v2:
- Drop applied patch
- Use device_get_match_data() as suggested by Bartosz
- Link to v1: https://patch.msgid.link/20251106-gpio-of-match-v1-0-50c7115a045e@linaro.org

Few simple cleanups, not tested on the hardware.

Care has to be taken when converting of_match_data() into
of_device_get_match_data(), because first can check arbitrary
device_node and the latter checks device's node.  Cases here should be
safe because of_match_data() uses 'pdev->dev.of_node'.

Best regards,
Krzysztof
