fbdev: pxa168fb: Remove redundant dev_err()

2026-08-10T06:13:25+00:00

Since commit 55b48e23f5c4 ("genirq/devres: Add error handling in devm_request_*_irq()"), devm_request_irq() automatically logs detailed error messages on failure. Remove the now-redundant driver-specific dev_err() call. Signed-off-by: Pan Chuang Signed-off-by: Helge Deller

fbdev: pxa168fb: use devm_ioremap_resource() for MMIO

2026-06-09T14:00:10+00:00

pxa168fb maps the LCD controller register resource with devm_ioremap(), which does not request the memory region. Use devm_ioremap_resource() instead so the MMIO range is claimed before being mapped. This also handles cleanup automatically. Signed-off-by: AlbertoArostegui Signed-off-by: Helge Deller

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/pxa168fb: Use fbdev I/O helpers

2023-08-04T13:54:37+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/20230803184034.6456-35-tzimmermann@suse.de

fbdev: Remove FBINFO_DEFAULT from framebuffer_alloc()'ed structs

2023-07-24T14:50:38+00:00

The flag FBINFO_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: Helge Deller Cc: Nicolas Ferre Cc: Benjamin Herrenschmidt Cc: Ferenc Bakonyi Cc: "K.

Do not assign the hardware device to struct fb_info.dev. The field references the fbdev software device, which is unrelated.

fbdev: pxa168fb: Convert to platform remove callback returning void

2023-04-24T09:48:31+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

fbdev: Move fbdev drivers from strlcpy to strscpy

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.
