If iga_init() fails, code releases resources and continues to use it. It seems that after releasing resources 'return' should be. Signed-off-by:

When we setup up the VMA flags for the mmap flag and we end up using the fallback mmap functionality we set the vma->vm_flags |= VM_IO. However we neglect to propagate the flag to the vma->vm_page_prot. This bug was found when Linux kernel was running under Xen. In that scenario, any page that has VM_IO flag to it, means that it MUST be a MMIO/VRAM backend memory , _not_ System RAM. That is what the fbmem.c does: sets VM_IO, ioremaps the region - everything is peachy. Well, not exactly. The vm_page_prot does not get the relevant PTE flags set (_PAGE_IOMAP) which under Xen is a death-kneel to pages that are referencing real physical devices but don't have that flag set. This patch fixes this. Signed-off-by:

Add a simple algorithm which calculates the pixel clock based on the video mode parameters. This is only done when no pixel clock is supplied through the platform data. This allows drivers to omit the pixel clock data and thus share the algorithm used for calculating it. Signed-off-by:

Supports all bpp modes. The PRTCON register is used to disable in-hardware updates of registers that store start and end addresses of framebuffer memory. This prevents display corruption in case we do not make it before VSYNC with updating them atomically. With this feature there is no need to wait for a VSYNC interrupt before each such update.

The following problems were found in the above situation: sfb->windows[win] was being assigned at the end of s3c_fb_probe_win only. This resulted in passing a NULL to s3c_fb_release_win if probe_win returned early and a memory leak. dma_free_writecombine does not allow its third argument to be NULL. fb_dealloc_cmap does not verify whether its argument is not NULL.

Update the variant and window variant structures with the necessary changes to support the older style of hardware where these are not in the same place. Add the support for the s3c2443/s3c2416 hardware by using the platform-device s3c2443 to cover both, and add the initialisation data for these. Also change to including just the v4 header files for the moment until the last of the merging of these is sorted out. Signed-off-by:

The driver clears all windows, but also sets the windows' colour key controls at the same time. However, the last window does not have these registers as it is always blended into the previous window. Move the colour key initialisation into the probe, and run it for only nr_win-1 windows.

It has been working fine at 16bpp but in case of pixel format more then 24bpp it would occur distortedness situation on that mode. so this patch set the word swap control bit of WINCONx to 1 as default value. but it should be set to 0 in case that each ENLOCAL bit of WINCON0 ~ 2 registers is enabled. this issue would be solved with local path feature soon.

Remove 43 section mismatches by moving the two structures efifb_defined and efifb_fix from .init.data to .devinit.data. Also the two structure arrays dmi_system_table[] and dmi_list[] have been moved from .data to .init.rodata and .init.data, which saves, if built-in, some space.

As sysfs_notify_dirent has been made irq safe, there is no reason to not call it directly from irq. With the work_struct removed, the remaining element in poll_desc is a sysfs_dirent pointer which may not be NULL. We can therefore store it directly in the idr and pass it as context to the irq handler. Most part of the patch deals with renaming defines and variables to reflect their new use without functional change. I also took the opportunity to initialize the idr statically. Signed-off-by:

The gpios on the max730x chips have support for internal pullups while in input mode. This patch adds support for configuring these pullups via platform data. A new member ("input_pullup_active") to the platform data struct is introduced. A set bit in this variable activates the pullups while the respective port is in input mode. This is a compatible enhancement since unset bits lead to disables pullups which was the default in the original driver. _Note_: the 4 lowest bits in "input_pullup_active" are unused because the first 4 ports of the controller are not used, too.

This patch does two modifications: (1) Adjust enable/disable IRQs location,enable it after rtc registration and disable it prior to unregistration. (2) Put 'platform_set_drvdata(pdev, nuc900_rtc)' in front of rtc registration still be safety, though there is no need to do this, when I move enable irq after rtc registration, I think still put 'platform_set_drvdata' before rtc registration that would be a good habit.
