regmap: rbtree: Fix overlapping rbnodes.

2013-09-08T05:10:00Z

commit 4e67fb5f5e336250db944921e3c68057d6203034 upstream. Avoid overlapping register regions by making the initial blklen of a new node 1. If a register write occurs to a yet uncached register, that is lower than but near an existing node's base_reg, a new node is created and it's blklen is set to an arbitrary value (sizeof(*rbnode)). That may cause this node to overlap with another node. Those nodes should be merged, but this merge doesn't happen yet, so this patch at least makes the initial blklen small enough to avoid hitting the wrong node, which may otherwise lead to severe breakage.

regmap: cache: Make sure to sync the last register in a block

2013-08-15T05:59:06Z

commit 2d49b5987561e480bdbd8692b27fc5f49a1e2f0b upstream. regcache_sync_block_raw_flush() expects the address of the register after last register that needs to be synced as its parameter. But the last call to regcache_sync_block_raw_flush() in regcache_sync_block_raw() passes the address of the last register in the block. This effectively always skips over the last register in a block, even if it needs to be synced. In order to fix it increase the address by one register. The issue was introduced in commit 75a5f89 ("regmap: cache: Write consecutive registers in a single block write").

regmap: cache: bail in regmap_async_complete() for bus-less maps

2013-08-04T08:50:58Z

commit f2e055e7c9c6084bfbaa68701e52562acf96419e upstream. Commit f8bd822cb ("regmap: cache: Factor out block sync") made regcache_rbtree_sync() call regmap_async_complete(), which in turn does not check for map->bus before dereferencing it. This causes a NULL pointer dereference on bus-less maps. Signed-off-by: Daniel Mack Signed-off-by: Mark Brown Signed-off-by: Greg Kroah-Hartman

regmap: rbtree: Fixed node range check on sync

2013-06-01T19:10:05Z

A node starting before the minimum register is no reason to reject it, since its end could be in range. The check for the end already exists two lines lower, so we can just remove the incorrect check. Signed-off-by: Maarten ter Huurne Signed-off-by: Mark Brown

regmap: regcache: Fixup locking for custom lock callbacks

2013-05-23T16:02:14Z

The parameter passed to the regmap lock/unlock callbacks needs to be map->lock_arg, regcache passes just map. This works fine in the case that no custom locking callbacks are used since in this case map->lock_arg equals map, but will break when custom locking callbacks are used. The issue was introduced in commit 0d4529c5("regmap: make lock/unlock functions customizable") and is fixed by this patch. Signed-off-by: Lars-Peter Clausen Signed-off-by: Mark Brown
