From: Lars-Peter Clausen Date: Thu, 16 Dec 2021 18:52:07 +0000 (+0100) Subject: iio: ad7192: Use sysfs_emit() X-Git-Tag: v6.1-rc5~1693^2~55^2~209 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9d5fcb8ffa69428d57761b43675407ce7f652fd0;p=platform%2Fkernel%2Flinux-starfive.git iio: ad7192: 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 `ac_excitation` and `bridge_swtich` attributes of the ad7192 driver.
