commit 97c44836cdec1ea713a15d84098a1a908157e68f upstream.

This patch makes the ROM reading code return an error to user space if
the size of the ROM read is equal to 0.

The patch also emits a warnings if the contents of the ROM are invalid,
and documents the effects of the "enable" file on ROM reading.

commit 1725b82a6e2721612a3572d0336f51f1f1c3cf54 upstream.

The changes specific for Samsung laptops seem unapplicable to other
hardware models like ASUS.  The mic inputs are lost on such hardware
by the change 5d5d5f43f1b835c375de9bd270cce030d16e2871.

This patch adds back the old laptop-eapd model, and create a new
model "samsung" for the new one specific to Samsung laptops with
automatic mic selection feature.

  ACPI: don't cond_resched() when irqs_disabled()
  ACPI: fix 2.6.28 acpi.debug_level regression

  ALSA: Fix a Oops bug in omap soc driver.
  ALSA: hda - Remove non-working headphone control for Dell laptops
  ALSA: hda - Add no-jd model for IDT 92HD73xx
  ALSA: Revert "ALSA: hda: removed unneeded hp_nid references"
  ALSA: hda - Add quirk for Dell Studio 17
  ALSA: hda - Fix silent HP output on D975

acpi_early_init() was changed to over-write the cmdline param,
making it really inconvenient to set debug flags at boot-time.

Also,
This sets the default level to "info", which is what all the ACPI
drivers use.  So to enable messages from drivers, you only have to
supply the "layer" (a.k.a. "component").  For non-"info" ACPI core
and ACPI interpreter messages, you have to supply both level and
layer masks, as before.

Added the model without the jack-detection for some desktops that
have really no jack-detection.  The recent driver caused regressions
regarding the sound output on such machines.

Signed-off-by: Takashi Iwai <tiwai@suse.de>

Some desktops seems to have no HP/mic jack detection on the front panel,
which results in the silent output in the recent driver, because the
driver mutes the output (to save power) when no plug is detected.

This patch adds a new model that disables the jack-detection.

This patch fixes a comment and clarifies the documentation about the
endianness of descriptors. The current policy is that descriptors will
be little-endian at the API even on big-endian systems; however the
/proc/bus/usb API predates this policy and presents descriptors with
some multibyte fields byte-swapped.

The example is incorrect: there is no 0t socket (the '1t' format has no
bus number in it). Also, correct the broken sentence for USB Tag.
