Merge tag 'regmap-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown: "This is a relatively busy release for regmap, though not busy in the grand scheme of things, with the addition of support for I3C from Vitor Soares and a few small fixes and cleanups" * tag 'regmap-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: select CONFIG_REGMAP while REGMAP_SCCB is set regmap: lzo: Switch to bitmap_zalloc() regmap: fix bulk writes on paged registers regmap: add i3c bus support regmap: debugfs: Fix memory leak in regmap_debugfs_init
