Subject: [PATCH 0799/1085] input: edt-ft5x06: Correct prefix length in
|
||
|
|
snprintf
|
||
|
|
|
||
|
|
snprintf takes the length of the array that we can print into,
|
||
|
|
and has to fit the NULL terminator in there too.
|
||
|
|
Printing the prefix is generally "12-3456 " which is 8 desired
|
||
|
|
characters (the length of EDT_NAME_PREFIX_LEN) and the NULL.
|
||
|
|
The space is therefore being truncated to fit the NULL in.
|
||
|
|
|
||
|
|
Increase the length snprintf is allowed to use.
|
||
|
