[PATCH] Fix NR_KEYS off-by-one error

From: OGAWA Hirofumi
Date: Fri Jul 16 2004 - 11:39:16 EST


KDGKBENT ioctl can use 256 entries (0-255), but it was defined as
key_map[NR_KEYS] (NR_KEYS == 255). The code seems also thinking it's 256.

key_map[0] = U(K_ALLOCATED);
for (j = 1; j < NR_KEYS; j++)
key_map[j] = U(K_HOLE);
