[PATCH 6.6 04/39] bus: fsl-mc: Replace snprintf and sprintf with sysfs_emit in sysfs show functions

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chelsy Ratnawat <chelsyratnawat2001@gmail.com>

[ Upstream commit a50522c805a6c575c80f41b04706e084d814e116 ]

Use sysfs_emit() instead of snprintf()/sprintf()  when writing
to sysfs buffers, as recommended by the kernel documentation.
