[PATCH] fbdev: fbmem: fix memory access if logo is bigger than the screen

2019-01-29 Thread Martin Kepplinger
From: Manfred Schlaegl There is no clipping on the x or y axis for logos larger that the framebuffer size. Therefore: a logo bigger than screen size leads to invalid memory access: [1.254664] Backtrace: [1.254728] [] (cfb_imageblit) from [] (fb_show_logo+0x620/0x684) [1.254763]
