VA-API version 1.22.0 LIBVA_DRIVER_NAME not work

[eric-gitta-moore]

It seems that the following if statement did not enter correctly.

libva/va/va.c

Lines 385 to 402 in df32686

	if (ctx->override_driver_name){
	if(*driver_name)

	if (!(*driver_name)) {
	va_errorMessage(dpy, "va_getDriverNameByIndex failed with %s, out of memory\n",vaErrorStr(VA_STATUS_ERROR_ALLOCATION_FAILED));
	return VA_STATUS_ERROR_ALLOCATION_FAILED;
	}
	va_infoMessage(dpy, "User requested driver '%s'\n", *driver_name);
	return VA_STATUS_SUCCESS;
	} else if (driver_name_env && (geteuid() == getuid())) {

Meanwhile, the other device was functioning normally. However, I noticed that the VAAPI versions of the two devices were not the same, but I couldn't determine which package caused the problem.
