Subject: wacom: patch for testing
|
|
Bug-Debian: http://bugs.debian.org/678798
|
|
|
|
When rep_data was an array
|
|
|
|
unsigned char rep_data[2];
|
|
|
|
spelling its address as &rep_data was perfectly valid, but now that
|
|
it is dynamically allocated
|
|
|
|
unsigned char *rep_data = kmalloc(2, GFP_KERNEL);
|
|
|
|
that expression returns a pointer to the pointer rather than to the
|
|
array itself. Regression introduced by commit f393ee2b814e (Input:
|
|
wacom - retrieve maximum number of touch points, 2012-04-29).
