fbdev/sh7760fb: Use fbdev I/O helpers

2023-08-04T13:54:38Z

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/20230803184034.6456-39-tzimmermann@suse.de

fbdev/sh7760fb: Use hardware device with dev_() output during probe

2023-06-27T07:58:50Z

Call output helpers in the probe function with the hardware device. The virtual fbdev device has not been initialized at that point. Also prepares fbdev for making struct fb_info.dev optional.

fbdev/sh7760fb: Alloc DMA memory from hardware device

2023-06-27T07:58:50Z

Pass the hardware device to the DMA helpers dma_alloc_coherent() and dma_free_coherent(). The fbdev device that is currently being used is a software device and does not provide DMA memory. Also update the related dev_*() output statements similarly.

fbdev: sh7760fb: Convert to platform remove callback returning void

2023-04-24T09:48:32Z

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
