[PATCH 1/4] staging: sm750fb: replace strcat() with memcpy() in lynxfb_setup()

[Artem Lytkin]

Replace deprecated strcat() with memcpy() in option parsing. The
destination buffer is allocated with kzalloc (zero-filled) and the
write position is tracked via pointer, making the null-terminator
scan in strcat() redundant and potentially unsafe.
