Subject: [PATCH v2 0/6] mmc: sdhci-pci: Add some CD GPIO related quirks

It appears that one of the supported platform magically worked with the
custom IRQ handler (any hints how?) while having two PCB designs with
an opposite CD sense level. Here is an attempt to fix it by quirking out
CD GPIO.

Patch 1 is an actual fix for the mentioned platform.
Patch 2 is code deduplication to save few LOCs.
Patch 3-6 are dead code removals.

In v2:
- redone fix to use ->get_cd() instead of quirks (Adrian)
- due to above transformed previous clean up to the current patch 2
- added a new patch, i.e. patch 3
- added commit IDs to patch 4 (Adrian)
- mentioned dependencies on previous patches in patch 5 and 6 (Adrian)

Andy Shevchenko (6):
  mmc: sdhci-pci: Read card detect from ACPI for Intel Merrifield
  mmc: sdhci: Deduplicate sdhci_get_cd_nogpio()
  mmc: sdhci: Remove unused prototype declaration in the header
  mmc: sdhci-pci: Remove dead code (struct sdhci_pci_data et al)
  mmc: sdhci-pci: Remove dead code (cd_gpio, cd_irq et al)
  mmc: sdhci-pci: Remove dead code (rst_n_gpio et al)
