The formula of Coverage alpha blending is: dst.a = dst.a * (0xff - src.a * SCA / 0xff) / 0xff + src.a * SCA / 0xff dst.a: destination alpha src.a: pixel alpha SCA : plane alpha When SCA = 0xff, the formula becomes: dst.a = dst.a * (0xff - src.a) + src.a This patch is to set the destination alpha (background) to 0xff: - When dst.a = 0 (before), dst.a = src.a - When dst.a = 0xff (after) , dst.a = 0xff * (0xff - src.a) + src.a According to the fomula above: - When src.a = 0 , dst.a = 0 - When src.a = 0xff, dst.a = 0xff This two cases are just still correct.

The mode_valid implementation had a call to drm_bridge_chain_mode_fixup() which would be wrong as the mode_valid is not allowed to change anything - only to validate the mode. As the next bridge is often/always a connector the call had no effect anyway. So drop it. From the git history I could see this call was included in the original version of the driver so there was no help there to find out why it was added in the first place. But a lot has changed since the initial driver were added and is seems safe to remove the call now. Signed-off-by:

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 ignored (apart from emitting a warning) 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. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

Occasionally, the generic/001 xfstest will fail indicating corruption in one of the copy chains when run on cifs against a server that supports FSCTL_DUPLICATE_EXTENTS_TO_FILE (eg. Samba with a share on btrfs). The problem is that the remote_i_size value isn't updated by cifs_setsize() when called by smb2_duplicate_extents(), but i_size *is*. This may cause cifs_remap_file_range() to then skip the bit after calling ->duplicate_extents() that sets sizes. Fix this by calling netfs_resize_file() in smb2_duplicate_extents() before calling cifs_setsize() to set i_size. This means we don't then need to call netfs_resize_file() upon return from ->duplicate_extents(), but we also fix the test to compare against the pre-dup inode size. [Note that this goes back before the addition of remote_i_size with the netfs_inode struct. It should probably have been setting cifsi->server_eof previously.] Fixes: cfc63fc8 ("smb3: fix cached file size problems in duplicate extents (reflink)") Signed-off-by:
