Subject: iio: ad9523: Use sysfs_emit()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=48788715ac8ed610a3d30ef1fb8d7fd38bdc1f81;p=linux.git

iio: ad9523: 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 device attributes of the ad9523
driver.
