* | lib: lodepng: remove useless testOleksij Rempel2018-11-211-7/+1
|/ | | | | | | | | | | | | | Either the condition 'code_ll==(unsigned int)(-1)' is redundant or the array 'LENGTHBASE[29]' is accessed at index 4294967038, which is out of bounds. On other hand this condition is tested within other scope: "if(code_ll >= FIRST_LENGTH_CODE_INDEX && code_ll <= LAST_LENGTH_CODE_INDEX)" with is already limited to (code_ll >= 257 && code_ll <= 285), so it can't be -1 any way.

* graphics_utils: Let fb_open allocate the screenSascha Hauer2015-07-203-35/+61

* graphics_utils: Export get_pixelSascha Hauer2015-07-161-2/+12
| | | | | | | | | | | get_pixel converts a 32bit trgb color into framebuffer format. This is useful for other code aswell, so export it. Other functions in the graphics utils code use the name get/set_pixel aswell, but instead of converting data they get a pixel from the framebuffer or set a pixel on the framebuffer. To separate from these rename the function to gu_hex_to_pixel. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
