If anyone has any objections, please let me know. ------------------ From: Saurabh Sengar [ Upstream commit f5e728a50bb17336a20803dde488515b833ecd1d ] The device object required in 'hvfb_release_phymem' function for 'dma_free_coherent' can also be obtained from the 'info' pointer, making 'hdev' parameter in 'hvfb_putmem' redundant. Remove the unnecessary 'hdev' argument from 'hvfb_putmem'.
