[PATCH] serial: i.MX: do not allow to build as module

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>

Commit f7d2c0bbdb (serial: i.MX: evaluate linux,stdout-path property) adds a
call to add_preferred_console() into drivers/tty/serial/imx.c. The file can be
built as module, yet add_preferred_console() is not exported.

Fix the build failure by disabling module build for the i.MX driver.
