Hello,

A change to the software ISP recently introduce hand-coded matrix
transposition. This is a feature that belongs to the Matrix class. This
small series adds a new Matrix::transpose() function and uses it in the
software ISP.

The code has been compile-tested only.

Laurent Pinchart (2):
  libcamera: matrix: Add a transpose() function
  libcamera: software_isp: debayer_egl: Use Matrix::transpose()
