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.
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).
