 * mipi_dsi_dual - send the same MIPI DSI command to two interfaces
 *
 * This macro will send the specified MIPI DSI command twice, once per each of
 * the two interfaces supplied. This is useful for reducing duplication of code
 * in panel drivers which use two parallel serial interfaces.
 *
 * Note that the _func parameter cannot accept a macro such as
 * mipi_dsi_generic_write_multi() or mipi_dsi_dcs_write_buffer_multi(). See
 * mipi_dsi_dual_generic_write_multi() and
 * mipi_dsi_dual_dcs_write_buffer_multi() instead.
 *
 * WARNING: This macro reuses the _func argument and the optional trailing
 * arguments twice each, which may cause unintended side effects. For example,
 * adding the postfix increment ++ operator to one of the arguments to be
 * passed to _func will cause the variable to be incremented twice instead of
 * once and the variable will be its original value + 1 when sent to _dsi2.
