This doesn't look like the right fix to me.
The line the compiler[1] complains about is:
*(unsigned short *) (CURS_PAT_REG + i * 8) = 0;
Interestingly, it doesn't complain about:
*(unsigned short *) (CURS_PAT_REG + 14 * 64) = 0xffff;
This driver uses raw memory writes to write to hardware registers.
Probably it should use writel() instead.
