commit bc22628591e5913e67edb3c2a89b97849e30a8f8 upstream.
The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature. Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().This patch fixes it by calling snd_card_free() on the error from the
probe callback using a new helper function.Fixes: 08e9d3ab4cc1 ("ALSA: es1938: Allocate resources with device-managed APIs")

This patch converts the resource management in PCI es1938 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.This should give no user-visible functional changes.

PCI ES1938 driver code contains a few assignments in if condition,
which is a bad coding style that may confuse readers and occasionally
lead to bugs.This patch is merely for coding-style fixes, no functional changes.

snd_soc_platform_driver structure or passed as the third argument to

As drvdata is cleared to NULL at probe failure or at removal by the
driver core, we don't have to call pci_set_drvdata(pci, NULL) any
longer in each driver.The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in
hda_intel.c. Since this function itself releases the card instance,
we need to clear drvdata here as well, so that it won't be released
doubly in the remove callback.Signed-off-by: Takashi Iwai

The semantics of snd_mpu401_uart_new()'s interrupt parameters are
somewhat counterintuitive: To prevent the function from allocating its
own interrupt, either the irq number must be invalid, or the irq_flags
parameter must be zero. At the same time, the irq parameter being
invalid specifies that the mpu401 code has to work without an interrupt
allocated by the caller. This implies that, if there is an interrupt
and it is allocated by the caller, the irq parameter must be set to
a valid-looking number which then isn't actually used.With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value,
which forces us to handle the parameters differently.This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the
device interrupt is handled by the caller, and makes the allocation of
the interrupt to depend only on the irq parameter. As suggested by
Takashi, the irq_flags parameter was dropped because, when used, it had
the constant value IRQF_DISABLED.Signed-off-by: Clemens Ladisch

The convention for pci_driver.name entry in kernel drivers seem to be
