drm: qxl: remove pr_info message, stops log spamming
Simply mmap'ing /dev/dri/card0 repeatedly will spam the kernel
log with qxl_mmap information messages. The following example code
illustrates this:
int main(void)
{
int fd = open("/dev/dri/card0", O_RDONLY);
if (fd == -1)
err(1, "open failed");
for (;;) {
void *m = mmap(NULL, 4096, PROT_READ,
MAP_SHARED, fd, 0);
if (m != MAP_FAILED)
munmap(m, 4096);
}
}
Stop the spamming by removing the pr_info message. Since the mmap'ing
returns -EINVAL there is no need for the pr_info message.
