video: fbdev: pxa3xx-gcu: release the resources correctly in pxa3xx_gcu_probe/remove()

2022-06-14T16:32:39Z

[ Upstream commit d87ad457f7e1b8d2492ca5b1531eb35030a1cc8f ] In pxa3xx_gcu_probe(), the sequence of error lable is wrong, it will leads some resource leaked, so adjust the sequence to handle the error correctly, and if pxa3xx_gcu_add_buffer() fails, pxa3xx_gcu_free_buffers() need be called. In pxa3xx_gcu_remove(), add missing clk_disable_unpreprare(). Signed-off-by: Yang Yingliang Signed-off-by: Helge Deller Signed-off-by: Sasha Levin

video: fbdev: hyperv_fb: Allow resolutions with size > 64 MB for Gen1

2022-06-14T16:32:38Z

[ Upstream commit c4b4d7047f16a8d138ce76da65faefb7165736f2 ] This patch fixes a bug where GEN1 VMs doesn't allow resolutions greater than 64 MB size (eg 7680x4320). Unnecessary PCI check limits Gen1 VRAM to legacy PCI BAR size only (ie 64MB). Thus any, resolution requesting greater then 64MB (eg 7680x4320) would fail. MMIO region assigning this memory shouldn't be limited by PCI bar size. Signed-off-by: Saurabh Sengar Reviewed-by: Dexuan Cui Signed-off-by: Helge Deller Signed-off-by: Sasha Levin

2022-06-09T08:21:20Z

[ Upstream commit b23789a59fa6f00e98a319291819f91fbba0deb8 ] of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak. Fixes: d10715be03bd ("video: ARM CLCD: Add DT support") Signed-off-by: Miaoqian Lin Signed-off-by: Helge Deller Signed-off-by: Sasha Levin

fbcon: Consistently protect deferred_takeover with console_lock()

2022-06-09T08:20:50Z

[ Upstream commit 43553559121ca90965b572cf8a1d6d0fd618b449 ] This shouldn't be a problem in practice since until we've actually taken over the console there's nothing we've registered with the console/vt subsystem, so the exit/unbind path that check this can't do the wrong thing. But it's confusing, so fix it by moving it a tad later.

parisc/stifb: Keep track of hardware path of graphics card

2022-06-09T08:20:49Z

commit b046f984814af7985f444150ec28716d42d00d9a upstream. Keep the pa_path (hardware path) of the graphics card in sti_struct and use this info to give more useful info which card is currently being used.

Fonts: Make font size unsigned in font_desc

2022-06-09T08:20:49Z

commit 7cb415003468d41aecd6877ae088c38f6c0fc174 upstream. `width` and `height` are defined as unsigned in our UAPI font descriptor `struct console_font`. Make them unsigned in our kernel font descriptor `struct font_desc`, too. Also, change the corresponding printk() format identifiers from `%d` to `%u`, in sti_select_fbfont().

commit cf936af790a3ef5f41ff687ec91bfbffee141278 upstream. Implement fb_is_primary_device() function, so that fbcon detects if this framebuffer belongs to the default graphics card which was used to start the system.
