Re: [PATCH] fix NULL pointer dereference in NOVA T USB2 Remote Control

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I've tried your repository a few minutes ago.
The card works (AGC) and te remote control as well (no NULL pointer exception).

What about this patch to remove unnecessary (and misleading) debug
output (it prints the values of the keys in the table up to the value
of the key pressed)?

I splitted the struct to take care about the changes. Can you please check
my repository? I'm always in hurry please forgive me in advance, if there
is another mistake.
