From: Lars-Peter Clausen Date: Thu, 16 Dec 2021 18:52:13 +0000 (+0100) Subject: iio: max31865: Use sysfs_emit() X-Git-Tag: v6.1-rc5~1693^2~55^2~203 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3c1d2fdd8096a08927ef3c5180208a136ac1a82b;p=platform%2Fkernel%2Flinux-starfive.git iio: max31865: Use 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_filter_notch_center_frequency` and fault_ovuv` device attributes of the max31865 driver.
