[v4,07/17] media: rzg2l-cru: Remove `channel` member from `struct rzg2l_cru_csi`

Commit Message

Lad, Prabhakar Oct. 7, 2024, 6:48 p.m. UTC

From: Lad Prabhakar <[e-mail]>

Remove the CSI virtual channel number from `struct rzg2l_cru_csi`.
Instead, pass the CSI virtual channel number as an argument to
`rzg2l_cru_csi2_setup()`.
