power: supply: smb347-charger: Fix interrupt usage if interrupt is unavailable

2021-03-04T11:14:44+00:00

[ Upstream commit 6996312642d2dad3070c3d276c7621f35e721f30 ]

The IRQ=0 could be a valid interrupt number in kernel because interrupt
numbers are virtual in a modern kernel. Hence fix the interrupt usage in
a case if interrupt is unavailable by not overriding the interrupt number
which is used by the driver.

Note that currently Nexus 7 is the only know device which uses SMB347
kernel diver and it has a properly working interrupt, hence this patch
doesn't fix any real problems, it's a minor cleanup/improvement.

power: supply: axp20x_usb_power: Init work before enabling IRQs

2021-03-04T11:14:43+00:00

[ Upstream commit b5e8642ed95ff6ecc20cc6038fe831affa9d098c ]

The IRQ handler calls mod_delayed_work() on power->vbus_detect. However,
that work item is not initialized until after the IRQs are enabled. If
an IRQ is already pending when the driver is probed, the driver calls
mod_delayed_work() on an uninitialized work item, which causes an oops.

power: supply: fix sbs-charger build, needs REGMAP_I2C

[ Upstream commit a4bdea2004b28f47ab48ea99172eda8628f6fb44 ]

CHARGER_SBS should select REGMAP_I2C since it uses API(s) that are
provided by that Kconfig symbol.

power: supply: cpcap-charger: Fix power_supply_put on null battery pointer

[ Upstream commit 39196cfe10dd2b46ee28b44abbc0db4f4cb7822f ]

Currently if the pointer battery is null there is a null pointer
dereference on the call to power_supply_put.  Fix this by only
performing the put if battery is not null.

power: supply: cpcap: Add missing IRQF_ONESHOT to fix regression

2021-03-04T11:14:31+00:00

[ Upstream commit e62333e26be649bfc3c167b9f2bbca38b92332c5 ]

Commit 25d76fed7ffe ("phy: cpcap-usb: Use IRQF_ONESHOT") started causing
errors loading phy-cpcap-usb driver:

cpcap_battery cpcap_battery.0: failed to register power supply
genirq: Flags mismatch irq 211. 00002080 (se0conn) vs. 00000080 (se0conn)

Let's fix this by adding the missing IRQF_ONESHOT to also cpcap-battery
and cpcap-charger drivers.
