fbdev: Switch back to struct platform_driver::remove()

2024-10-08T19:47:18+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/video/fbdev to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files. Signed-off-by: Uwe Kleine-König Reviewed-by: Thomas Zimmermann Signed-off-by: Helge Deller

fbdev: goldfishfb: Do not check 0 for platform_get_irq()

2023-08-15T21:39:33+00:00

Since platform_get_irq() never returned zero, so it need not to check whether it returned zero, and we use the return error code of platform_get_irq() to replace the current return error code. Please refer to the commit a85a6c86c25b ("driver core: platform: Clarify that IRQ 0 is invalid") to get that platform_get_irq() never returned zero.

fbdev/goldfishfb: Use fbdev I/O helpers

2023-08-04T13:54:36+00:00

Set struct fb_ops and with FB_DEFAULT_IOMEM_OPS, fbdev's initializer for I/O memory. Sets the callbacks to the cfb_ and fb_io_ functions. Select the correct modules with Kconfig's FB_IOMEM_HELPERS token. The macro and token set the currently selected values, so there is no functional change. v3: * use _IOMEM_ in commit message v2: * updated to use _IOMEM_ tokens Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Acked-by: Helge Deller Link: https://patchwork.freedesktop.org/patch/msgid/20230803184034.6456-17-tzimmermann@suse.de

fbdev: Remove FBINFO_FLAG_DEFAULT from framebuffer_alloc()'ed structs

2023-07-24T14:50:39+00:00

The flag FBINFO_FLAG_DEFAULT is 0 and has no effect, as struct fbinfo.flags has been allocated to zero by framebuffer_alloc(). So do not set it. Flags should signal differences from the default values. After cleaning up all occurrences of FBINFO_DEFAULT, the token will be removed. v4: * clarify commit message (Geert, Dan) v2: * fix commit message (Miguel) Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Cc: Jaya Kumar Cc: Helge Deller Cc: Peter Jones Cc: Sascha Hauer Cc: Pengutronix Kernel Team Cc: Shawn Guo Cc: Fabio Estevam Cc: NXP Linux Team Cc: Maik Broemme Cc: Jingoo Han Cc: Sudip Mukherjee Cc: Teddy Wang Cc: Michal Januszewski Link: https://patchwork.freedesktop.org/patch/msgid/20230715185343.7193-15-tzimmermann@suse.de

fbdev: goldfishfb: Convert to platform remove callback returning void

2023-04-24T09:48:30+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Helge Deller

video: constify fb ops across all drivers

2019-12-05T08:57:53+00:00

Now that the fbops member of struct fb_info is const, we can start making the ops const as well. This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it. v3: - un-constify atyfb, mb862xx, nvidia and uvesabf (0day) v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com
