Date: Sat, 17 Feb 2024 16:42:34 +0000 Message-ID: <20240217164249.921878-1-jic23@kernel.org> X-Mailer: git-send-email 2.43.2 Precedence: bulk X-Mailing-List: linux-acpi@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 From: Jonathan Cameron Sorry for the rapid resend, Andy noticed I'd messed up creating the v3 patch set with some updates committed in the wrong patch. Since v3: The updates to alignment of device_for_each_child_node_scopd() were in the wrong patch. Move them to patch 4 where they should always have been. (thanks Andy!) Since v2: Thanks to Sakari and Andy for reviews. - New first patch moving fwnode_handle_put() into property.h - Tweak alignment in the loop macro - Pick up tags. - scopd -> scoped typo fix in some patch descriptions. As can be seen by the examples from IIO that follow this can save a reasonable amount of complexity and boiler plate code, often enabling additional cleanups in related code such as use of return dev_err_probe(). Given we are now fairly late in the cycle, I'd expect to take this through the IIO tree and we can make use of it elsewhere next cycle. Note I don't have the hardware so this is compile tested only. Hence I'd appreciate some Tested-by tags if anyone can poke one of the effected drivers. Julia Lawal has posted some nice coccinelle magic for the DT equivalents. Referenced from that cover letter. Similar may help us convert more drivers to use this new approach, but often hand tweaking can take additional advantage of other cleanup.h based magic, or things like return dev_err_probe(). https://lore.kernel.org/all/20240211174237.182947-1-jic23@kernel.org/ Jonathan Cameron (15): device property: Move fwnode_handle_put() into property.h device property: Add cleanup.h based fwnode_handle_put() scope based cleanup. iio: temp: ltc2983: Use __free(fwnode_handle) to replace fwnode_handle_put() calls device property: Introduce device_for_each_child_node_scoped() iio: adc: max11410: Use device_for_each_child_node_scoped() iio: adc: mcp3564: Use device_for_each_child_node_scoped() iio: adc: qcom-spmi-adc5: Use device_for_each_child_node_scoped() iio: adc: rzg2l_adc: Use device_for_each_child_node_scoped() iio: adc: stm32: Use device_for_each_child_node_scoped() iio: adc: ti-ads1015: Use device_for_each_child_node_scoped() iio: adc: ti-ads131e08: Use device_for_each_child_node_scoped() iio: addac: ad74413r: Use device_for_each_child_node_scoped() iio: dac: ad3552r: Use device_for_each_child_node_scoped() iio: dac: ad5770r: Use device_for_each_child_node_scoped() iio: dac: ltc2688: Use device_for_each_child_node_scoped() drivers/base/property.c | 14 ------ drivers/iio/adc/max11410.c | 27 +++-------- drivers/iio/adc/mcp3564.c | 16 +++---- drivers/iio/adc/qcom-spmi-adc5.c | 7 +-- drivers/iio/adc/rzg2l_adc.c | 11 ++--- drivers/iio/adc/stm32-adc.c | 63 ++++++++++--------------- drivers/iio/adc/ti-ads1015.c | 5 +- drivers/iio/adc/ti-ads131e08.c | 13 ++---- drivers/iio/addac/ad74413r.c | 10 +--- drivers/iio/dac/ad3552r.c | 51 ++++++++------------- drivers/iio/dac/ad5770r.c | 19 +++----- drivers/iio/dac/ltc2688.c | 24 +++------- drivers/iio/temperature/ltc2983.c | 76 ++++++++++--------------------- include/linux/property.h | 22 ++++++++- 14 files changed, 126 insertions(+), 232 deletions(-)
