Merge tag 'mfd-fixes-5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd
Pull mfd bugfix from Lee Jones.
Fix stmfx type confusion between regmap_read() (which takes an "u32")
and the bitmap operations (which take an "unsigned long" array).
* tag 'mfd-fixes-5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd:
mfd: stmfx: Fix an endian bug in stmfx_irq_handler()
mfd: stmfx: Uninitialized variable in stmfx_irq_handler()
