[PATCH] leds: class-flash: use sysfs_emit() instead of sprintf()

[Akshat Rawat <akshatrawat095@gmail.com>]

Use sysfs_emit() instead of sprintf() in sysfs show callbacks
(flash_brightness_show, max_flash_brightness_show, flash_strobe_show,
flash_timeout_show, and max_flash_timeout_show) to conform to the
recommended sysfs attribute formatting guidelines in
Documentation/filesystems/sysfs.rst.
