[ Upstream commit c2c0b67dca3cb3b3cea0dd60075a1c5ba77e2fcd ]
The tas2781-i2c driver gets an IRQ from either ACPI or device tree,
then proceeds to check if the IRQ has a corresponding GPIO and in
case it does enforce the GPIO as input and set a label on it.
This is abuse of the API:
- First we cannot guarantee that the numberspaces of the GPIOs and
the IRQs are the same, i.e that an IRQ number corresponds to
a GPIO number like that.
- Second, GPIO chips and IRQ chips should be treated as orthogonal
APIs, the irqchip needs to ascertain that the backing GPIO line
is set to input etc just using the irqchip.
- Third it is using the legacy <linux/gpio.h> API which should not
be used in new code yet this was added just a year ago.
Delete the offending code.
If this creates problems the GPIO and irqchip maintainers can help
to fix the issues.
It *should* not create any problems, because the irq isn't
used anywhere in the driver, it's just obtained and then
left unused.

The acpi_subysystem_id is only written and freed, not read, so
unnecessary.

commit 34a1066981a967eab619938e7b35a9be6b4c34e1 upstream.
The tascodec_init() of the snd-soc-tas2781-comlib module is called from
snd-soc-tas2781-i2c and snd-hda-scodec-tas2781-i2c modules. It calls
request_firmware_nowait() with parameter THIS_MODULE and a cont/callback
from the latter modules.
The latter modules can be removed while their callbacks are running,
resulting in a general protection failure.
Add module parameter to tascodec_init() so request_firmware_nowait() can
be called with the module of the callback.
