ACPI: configfs: Use sysfs_emit() in "show" functions
The sysfs_emit() function was introduced to make it less ambiguous which function is preferred when writing to the output buffer in a "show" callback [1]. Convert the GPIO library sysfs interface from sprintf() to sysfs_emit() accordingly, as the latter is aware of the PAGE_SIZE buffer and correctly returns the number of bytes written into the buffer. No functional change intended. [1] Documentation/filesystems/sysfs.rst Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
