Rework the patch to completely disable yenta_probe_irq function.
The generated mask is zero by lack due to the fact that probe_irq_mask
use a val never initialized. Correctly rework the ifdef to make the
function always return 0.
Fix compilation warning:
drivers/pcmcia/yenta_socket.c:926:13: error: unused variable 'i' [-Werror=unused-variable]
926 | int i;
| ^
drivers/pcmcia/yenta_socket.c:954:16: error: 'val' is used uninitialized [-Werror=uninitialized]
954 | mask = probe_irq_mask(val) & 0xffff;
| ^~~~~~~~~~~~~~~~~~~
drivers/pcmcia/yenta_socket.c:927:23: note: 'val' was declared here
927 | unsigned long val;
| ^~~
