strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading
to all kinds of misbehaviors. So, this serie removes all strcpy uses
from the "staging/fbtft" subsystem.

Also, refactor the code a bit to follow the kernel coding-style and
avoid unnecessary variable initialization.

I don't see patch 3 (even on lore.kernel.org).

Greg, Geert, does it make sense to move this driver outside of staging?
I would volunteer to maintain it there.

Changelog v1 -> v2
- Add two new commits to clean the code.
- Use the "%*ph" format specifier instead of strscpy() function (Geert
  Uytterhoeven)

Changelog v2 -> v3
- Change the initialization of the "j" variable in the "for" loop and
  update the code accordingly (Andy Shevchenko).
- Improve the commit message to inform that the "%*ph" replacement
  won't cut output earlier than requested (Andy Shevchenko).
- Don't remove the braces in the "if" statement due to the presence of
  the comment (Geert Uytterhoeven).
