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