[PATCH v3] fbdev: s1d13xxxfb: add missed unregister_framebuffer in remove

From: Chuhong Yuan
Date: Tue Mar 24 2020 - 09:30:16 EST


The driver calls register_framebuffer() in probe but does not call
unregister_framebuffer() in remove.
Rename current remove to __s1d13xxxfb_remove() for error handler.
Then add a new remove to call unregister_framebuffer().

Changes in v3:
- Fix code style.
- Set __s1d13xxxfb_remove() to return void.
- Remove redundant check for info.
