From 748c7ebac8dbcf54c2840a9a74fc9efeb4d76b7f Mon Sep 17 00:00:00 2001 From: Li Zhijian Date: Thu, 14 Mar 2024 17:58:13 +0800 Subject: fbdev: uvesafb: Convert sprintf/snprintf to sysfs_emit Per filesystems/sysfs.rst, show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space. coccinelle complains that there are still a couple of functions that use snprintf(). Convert them to sysfs_emit(). sprintf() will be converted as weel if they have.
