There are only two callers that use the returned code from unregister_console(): - unregister_early_console() in arch/m68k/kernel/early_printk.c - kgdb_unregister_nmi_console() in drivers/tty/serial/kgdb_nmi.c They both expect to get "0" on success and a non-zero value on error. But the current behavior is confusing and buggy: - _braille_unregister_console() returns "1" on success - unregister_console() returns "1" on error Fix and clean up the behavior: - Return success when _braille_unregister_console() succeeded - Return a meaningful error code when the console was not registered before Link: http://lkml.kernel.org/r/20200203133130.11591-5-andriy.shevchenko@linux.intel.com To: linux-kernel@vger.kernel.org To: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Signed-off-by: Petr Mladek <pmladek@suse.com> |
