Modify scale to convert from ppm/ppb to percentage: 1 ppm = 0.0001% 1 ppb = 0.0000001% There is no offset needed to convert the ppm/ppb to percentage, so remove offset from IIO_CONCENTRATION (IIO_MOD_CO2) channel.

When a thread that uses epoll explicitly exits using BINDER_THREAD_EXIT, the waitqueue is freed, but it is never removed from the corresponding epoll data structure.

[Linux-stable-mirror] [PATCH 4.9] usbip: vhci_hcd: clear just the USB_PORT_STAT_POWER bit

by Shuah Khan

Upstream commit 1c9de5bf4286 ("usbip: vhci-hcd: Add USB3 SuperSpeed support") vhci_hcd clears all the bits port_status bits instead of clearing just the USB_PORT_STAT_POWER bit when it handles ClearPortFeature: USB_PORT_FEAT_POWER. This causes vhci_hcd attach to fail in a bad state, leaving device unusable by the client. The device is still attached and however client can't use it. The problem was fixed as part of larger change to add USB3 Super Speed support. This patch backports just the change to clear the USB_PORT_STAT_POWER.

Quoting Hans: If we return 1 from our post_reset handler, then our disconnect handler will be called immediately afterwards. Since pre_reset blocks all scsi requests our disconnect handler will then hang in the scsi_remove_host call. This is esp. bad because our disconnect handler hanging for ever also stops the USB subsys from enumerating any new USB devices, causes commands like lsusb to hang, etc. In practice this happens when unplugging some uas devices because the hub code may see the device as needing a warm-reset and calls usb_reset_device before seeing the disconnect. In this case uas_configure_endpoints fails with -ENODEV. We do not want to print an error for this, so this commit also silences the shost_printk for -ENODEV. ENDQUOTE However, if we do that we better drop any unconditional execution and report to the SCSI subsystem that we have undergone a reset but we are not operational now.
