[PATCH AUTOSEL 4.9 1/5] bus: sunxi-rsb: Return correct data when mixing 16-bit and 8-bit reads
From: Ondrej Jirman megous@megous.com
[ Upstream commit a43ab30dcd4a1abcdd0d2461bf1cf7c0817f6cd3 ]
When doing a 16-bit read that returns data in the MSB byte, the RSB_DATA register will keep the MSB byte unchanged when doing the following 8-bit read. sunxi_rsb_read() will then return a result that contains high byte from 16-bit read mixed with the 8-bit result.
The consequence is that after this happens the PMIC's regmap will look like this: (0x33 is the high byte from the 16-bit read)
% cat /sys/kernel/debug/regmap/sunxi-rsb-3a3/registers 00: 33 01: 33 02: 33 03: 33 04: 33 05: 33 06: 33 07: 33 08: 33 09: 33 0a: 33 0b: 33 0c: 33 0d: 33 0e: 33 [snip]
Fix this by masking the result of the read with the correct mask based on the size of the read. There are no 16-bit users in the mainline kernel, so this doesn't need to get into the stable tree.

printk in macro vxge_debug_ll uses __VA_ARGS__ without "##" prefix, it causes a build error when there is no variable arguments(e.g. only fmt is specified.).

Currently, the -EEXIST return code of ->insert() callbacks is ambiguous: it might indicate that a given element (including intervals) already exists as such, or that the new element would clash with existing ones.
If identical elements already exist, the front-end is ignoring this without returning error, in case NLM_F_EXCL is not set. However, if the new element can't be inserted due an overlap, we should report this to the user.
To this purpose, allow set back-ends to return -ENOTEMPTY on collision with existing elements, translate that to -EEXIST, and return that to userspace, no matter if NLM_F_EXCL was set.
