[PATCHv1 01/19] kobject: increase allowed number of uevent variables

From: Sebastian Reichel
Date: Wed May 13 2020 - 14:58:02 EST


SBS battery driver exposes 32 power supply properties now,
which will result in uevent failure on (un)plugging the
battery. Other drivers (e.g. bq27xxx) are also coming close
to this limit, so increase it.
