[15/23] media: imx: imx7_mipi_csis: Don't pass pdev to mipi_csis_parse_dt()

Commit Message

Laurent Pinchart April 13, 2021, 2:30 a.m. UTC

The mipi_csis_parse_dt() function is called with a pointer to the
csi_state, which contains all the information necessary. Don't pass the
platform device pointer as well.
