From e9d4397a1627ea4e30c1f1fe9f2889bb31d658f2 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Thu, 16 Dec 2021 19:52:10 +0100 Subject: [PATCH] iio: ina2xx-adc: sysfs_emit() sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it knows about the sysfs buffer specifics and has some built-in checks for size and alignment. Use sysfs_emit() to format the custom `in_allow_async_readout` device attribute of the ina2xx-adc driver.
