[v3,1/2] fbdev: hyperv_fb: Simplify hvfb_putmem

Commit Message

Saurabh Sengar March 1, 2025, 4:16 p.m. UTC

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'.
