Retain the previous error values as debug messages
instead.
Well, they are not really useful because they are actually undocumented.instead.
+ if (version != KEY_MAP_VER) {
+ pr_debug("Version mismatch %d\n", -1);
Rather print version and KEY_MAP_VER+ pr_debug("Version mismatch %d\n", -1);
+ if (key_data_len + SHIFT_TBL_SIZE + 4 >= sizeof(spk_key_buf)) {
+ pr_debug("Data len and Shift table too big %d\n", -2);
Rather print key_data_len + SHIFT_TBL_SIZE + 4 and sizeof(spk_key_buf)+ pr_debug("Data len and Shift table too big %d\n", -2);
+ if (ch >= SHIFT_TBL_SIZE) {
+ pr_debug("Key table size overflow %d\n", -3);
Rather print ch and SHIFT_TBL_SIZE.+ pr_debug("Key table size overflow %d\n", -3);
+ if (ch >= MAX_KEY) {
+ pr_debug("Max Key overflow %d\n", -4);
Rather print ch and MAX_KEY.+ pr_debug("Max Key overflow %d\n", -4);
Apart from that, returning -EINVAL instead of different values is fine
for me.
