#     Merge tag 'for-v5.1-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply
#     
#     Pull power supply fixes from Sebastian Reichel:
#      "Two more fixes for the 5.1 cycle.
#     
#       One division by zero fix in a specific driver and one core workaround
#       for bad userspace behaviour from systemd regarding uevents. IMHO this
#       can be considered to be a userspace bug, but the debug messages are
#       useless anyways
#     
#        - cpcap-battery: fix a division by zero
#     
#        - core: fix systemd issue due to log messages produced by uevent"
#     
#     * tag 'for-v5.1-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-power-supply:
#       power: supply: sysfs: prevent endless uevent loop with CONFIG_POWER_SUPPLY_DEBUG
#       power: supply: cpcap-battery: Fix division by zero
