Some HID devices are looking on the unused bits in the HID reports they receive. This is violating the specification, but we want to make those devices work. Well-behaving devices are unaffected, as they don't care about the unused bits. If bitsused % 8 is 0 all bits in data[] get used and we don't need to clear anything. Otherwise (bitsused % 8) bits of the last byte get used. By shifting 1 for (bitsused % 8) bits and subtracting 1 we create a mask consisting of (bitsused % 8) ones and remaining zeroes. By ANDing we clear the upper unused bits. Signed-off-by: Simon Budig <simon@budig.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz> |
