Subject: [PATCH v6 14/23] media: rzg2l-cru: Inline calculating bytesperline

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Remove the `rzg2l_cru_format_bytesperline()` function and inline the
calculation of `bytesperline` directly in `rzg2l_cru_format_align()`.
This simplifies the code by removing an unnecessary function call and
directly multiplying the image width by the `bpp` (bytes per pixel)
from the format structure.
