linux-next/drivers/gpu/drm/rockchip/dw-mipi-dsi.c:470: poor error checking ?

[David Binderman]

Hello there,

[linux-next/drivers/gpu/drm/rockchip/dw-mipi-dsi.c:470]: (style) Checking if 
unsigned variable 'bpp' is less than zero.

    bpp = mipi_dsi_pixel_format_to_bpp(dsi->format);
    if (bpp < 0) {

but

  unsigned int bpp, i, pre;

Suggest code rework.


Regards
