#1728897 — [PATCH 4.9 10/32] iio: adc: ti-ads1015: enable conversion when CONFIG_PM is not set

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Akinobu Mita <akinobu.mita@gmail.com>

commit e8245c68350104b6022b6783719e843d69ea7c43 upstream.

The ADS1015 device have two operating modes, continuous conversion mode
and single-shot mode.  This driver assumes that the continuous conversion
mode is selected by runtime resume callback when the ADC result is
requested.

If CONFIG_PM is disabled, the device is always in the default single-shot
mode and no one begins a single conversion.  So the conversion register
doesn't contain valid ADC result.  Fix it by changing the continuous mode
in probe function.

#1728898 — [PATCH 4.9 19/32] rtlwifi: rtl_pci_probe: Fix fail path of _rtl_pci_find_adapter

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Malcolm Priestley <tvboxspy@gmail.com>

commit fc81bab5eeb103711925d7510157cf5cd2b153f4 upstream.

_rtl_pci_find_adapter fail path will jump to label fail3 for
unsupported adapter types.

However, on course for fail3 there will be call rtl_deinit_core
before rtl_init_core.

For the inclusion of checking pci_iounmap this fail can be moved to
fail2.

#1728900 — [PATCH 4.9 01/32] usb: quirks: add delay init quirk for Corsair Strafe RGB keyboard

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kai-Heng Feng <kai.heng.feng@canonical.com>

commit de3af5bf259d7a0bfaac70441c8568ab5998d80c upstream.

Corsair Strafe RGB keyboard has trouble to initialize:

[ 1.679455] usb 3-6: new full-speed USB device number 4 using xhci_hcd
[ 6.871136] usb 3-6: unable to read config index 0 descriptor/all

[ 22.997715] usb 3-6: unable to read config index 0 descriptor/all
[ 22.997716] usb 3-6: can't read configurations, error -110

Although it may work after several times unpluging/pluging:

[ 68.195240] usb 3-6: new full-speed USB device number 11 using xhci_hcd
[ 68.337459] usb 3-6: New USB device found, idVendor=1b1c, idProduct=1b20
[ 68.337463] usb 3-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 68.337466] usb 3-6: Product: Corsair STRAFE RGB Gaming Keyboard
[ 68.337468] usb 3-6: Manufacturer: Corsair
[ 68.337470] usb 3-6: SerialNumber: 0F013021AEB8046755A93ED3F5001941

Tried three quirks: USB_QUIRK_DELAY_INIT, USB_QUIRK_NO_LPM and
USB_QUIRK_DEVICE_QUALIFIER, user confirmed that USB_QUIRK_DELAY_INIT alone
can workaround this issue. Hence add the quirk for Corsair Strafe RGB.
