From c3154def82fc6b6fb59fd4520cbc2f92211c109d Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Thu, 16 Dec 2021 19:52:05 +0100 Subject: iio: core: 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. This patch converts the places in the IIO core that follow the pattern of return s*printf(...) to return sysfs_emit(...) This covers the new places that have been introduced where sprintf() is used for formatting sysfs output since the last time this was done in commit 83ca56b663cf ("iio: core: Use sysfs_emit() (trivial bits)").
