stable inclusion from linux-4.19.207 commit c1c3b899fb5d481c2a0ea99f259be44b1115e209
--------------------------------
[ Upstream commit caa534c3ba40c6e8352b42cbbbca9ba481814ac8 ]
When fuel_gauge_reg_readb()/_writeb() fails, report which register we were trying to read / write when the error happened.
Also reword the message a bit: - Drop the axp288 prefix, dev_err() already prints this - Switch from telegram / abbreviated style to a normal sentence, aligning the message with those from fuel_gauge_read_*bit_word()
