SubjectApplied "regmap: Remove attribute packed from struct 'regcache_rbtree_node'" to the regmap tree
The patch

regmap: Remove attribute packed from struct 'regcache_rbtree_node'

has been applied to the regmap tree at

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Subject: [PATCH] regmap: Remove attribute packed from struct

On one hand commit 28644c809f44 ("regmap: Add the rbtree cache support")
added 'regcache_rbtree_node' as packed structure, while on the other hand
commit e977145aeaad ("[RBTREE] Add explicit alignment to sizeof(long)
for struct rb_node.") declared struct 'rb_node' as aligned.

Solve the ambiguity of placing aligned structure in a packed one by
removing the packed attribute from struct. This seems to be the behavior
of gcc anyway.

This removes the following warning (W=1):

drivers/base/regmap/regcache-rbtree.c:36:1: warning: alignment 1 of 'struct regcache_rbtree_node' is less than 4 [-Wpacked-not-aligned]
