#     Merge tag 'pwm/for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
#     
#     Pull pwm updates from Thierry Reding:
#      "Besides one new driver being added for the PWM controller found in
#       various Spreadtrum SoCs, this series of changes brings a slew of,
#       mostly minor, fixes and cleanups for existing drivers, as well as some
#       enhancements to the core code.
#     
#       Lastly, Uwe is added to the PWM subsystem entry of the MAINTAINERS
#       file, making official his role as a reviewer"
