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.
