Subject: [PATCH -next v2 0/3] iio: adc: at91_adc: Cleanup with the helpers
Date: Sat, 26 Aug 2023 10:29:19 +0800	[thread overview]
Message-ID: <20230826022922.3457054-1-ruanjinjie@huawei.com> (raw)

Commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared
and enabled clocks") provides a new helper function to prepare and
enable a clock which keeps prepared (or enabled) during the whole
lifetime of the driver.

Use devm_request_irq() to request the interrupt, so we can
avoid having to manually clean this up.

Use the dev_err_probe() helper to simplify error handling during probe.
This also handle scenario, when EDEFER is returned and useless
error is printed.

Changes in v2:
- Also use devm_request_irq() and dev_err_probe() to clean up the at91_adc.
- Split the at91_adc patch out to be a new patch set.

Jinjie Ruan (3):
  iio: adc: at91_adc: Use devm_clk_get_enabled() helper function
  iio: adc: at91_adc: Use devm_request_irq() helper function
  iio: adc: at91_adc: Simplify with dev_err_probe()
