From 718fb2bcf1034232599045fc710644d903c2af4b Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Thu, 13 May 2021 15:07:45 +0300 Subject: iio: adc: ad_sigma_delta: introduct devm_ad_sd_setup_buffer_and_trigger() This is a version of ad_sd_setup_buffer_and_trigger() with all underlying functions (that are used) being replaced with their device-managed variants. One thing to take care here is with {devm_}iio_trigger_alloc(), where both functions take a parent-device object as the first parameter. To make sure nothing quirky is happening, the devm_ad_sd_probe_trigger() function is checking that the provided 'dev' reference is the same as the one stored on the 'struct ad_sigma_delta' driver data.
