Subject: decode_tm6000: fix compiler warning
Author: Hans Verkuil <hverkuil-ci...@xs4all.nl>
Date: Mon Nov 8 11:14:07 2021 +0100
decode_tm6000.c: In function ‘main’:
decode_tm6000.c:354:25: warning: ‘img’ may be used uninitialized
[-Wmaybe-uninitialized]
354 | memcpy(buf,&img[pos],sizeof(buf));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
decode_tm6000.c:253:48: note: ‘img’ declared here
253 | unsigned char buf[TM6000_URB_MSG_LEN], img[720*2*480];
| ^~~
Just initialize img to all 0.
