[PATCH] staging: atomisp: replace sprintf with strscpy

[tomasz . unger]

From: Tomasz Unger <tomasz.unger@xxxxxxxx>

Replace deprecated sprintf() with strscpy() which is the preferred
kernel API for string copying. strscpy() is safer as it guarantees
null-termination and prevents potential buffer overflows.

Since sd->name is a fixed-size array, the destination buffer size
is deduced automatically by the kernel-defined strscpy() macro,
so no explicit size parameter is needed.

Compiled and tested by loading atomisp.ko module successfully.
