media: pvrusb2: use a different format for warnings
When the pvrusb2 driver detects that there's something wrong with the device, it prints a warning message. Right now those message are printed in two different formats: 1. ***WARNING*** message here 2. WARNING: message here There's an issue with the second format. Syzkaller recognizes it as a message produced by a WARN_ON(), which is used to indicate a bug in the kernel. However pvrusb2 prints those warnings to indicate an issue with the device, not the bug in the kernel. This patch changes the pvrusb2 driver to consistently use the first warning message format. This will unblock syzkaller testing of this driver. Reported-by:<syzbot+af8f8d2ac0d39b0ed3a0@syzkaller.appspotmail.com> Reported-by:
