From: Santosh Yaraganavi <santoshsy@xxxxxxxxx> UTP Transfer request list base registers UTRLBA and UTRLBAU must be assigned, lower-32 and upper-32 bits of UTRLD list physical base addresses respectively. Currently UTRLBAU is being assigned lower-32 bits of UTRLD physical base address. This will cause an issue with controllers that can support 64-bit addressing. This patch correctly assigns upper-32 bits of UTRLD physical base address to UTRLBAU.
