From 4d38e5c48f4095be21343869ad741676ab4e518f Mon Sep 17 00:00:00 2001 From: James Hogan Date: Fri, 5 Jun 2015 22:17:18 +0100 Subject: tty/metag_da: Avoid module_init/module_exit in non-modular code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The metag_da TTY driver can't get built as a module at the moment, but it still uses module_init() and module_exit(). Those macros are moving to module.h which isn't included by metag_da.c, which will result in the following build warnings (remarkably no build errors) and an apparent failure to boot as the TTY driver won't be loaded. drivers/tty/metag_da.c:660: warning: data definition has no type or storage class drivers/tty/metag_da.c:660: warning: type defaults to ‘int’ in declaration of ‘module_init’ drivers/tty/metag_da.c:660: warning: parameter names (without types) in function declaration drivers/tty/metag_da.c:661: warning: data definition has no type or storage class drivers/tty/metag_da.c:661: warning: type defaults to ‘int’ in declaration of ‘module_exit’ drivers/tty/metag_da.c:661: warning: parameter names (without types) in function declaration drivers/tty/metag_da.c:572: warning: ‘dashtty_init’ defined but not used drivers/tty/metag_da.c:645: warning: ‘dashtty_exit’ defined but not used drivers/tty/metag_da.c In function ‘dash_console_write’: drivers/tty/metag_da.c:670 : warning: passing argument 4 of ‘chancall’ discards qualifiers from pointer target type Instead of just adding the module.h include, now would be a good time to remove the use of these macros, replacing the module_init with device_initcall, and removing the exit function altogether since it isn't needed. If module support is added later the code can always be resurrected.
