2019-11-20intel_th: Fix a double put_device() in error pathAlexander Shishkin
Commit a753bfcfdb1f ("intel_th: Make the switch allocate its subdevices") factored out intel_th_subdevice_alloc() from intel_th_populate(), but got the error path wrong, resulting in two instances of a double put_device() on a freshly initialized, but not 'added' device.

2019-11-20fbtft: Drop useless #ifdef CONFIG_OF and dead codeAndy Shevchenko
First of all there is no need to guard GPIO request by CONFIG_OF. It works for everybody independently on resource provider. While here, rename the function to reflect the above. Moreover, since we have a global dependency to OF, the rest of conditional compilation is no-op, i.e. it's always be true. Due to above drop useless #ifdef CONFIG_OF and therefore dead code.

2019-11-20Revert "mt76: mt76x0e: don't use hw encryption for MT7630E"Stanislaw Gruszka
This reverts commit 34b0e9b767bfa09ae233ca0d6ceb299bf2e24600. Since commit 7bd0650be63c ("mt76: dma: fix buffer unmap with non-linear skbs") is no longer necessary to disable HW encryption for MT7630E. Disabling HW encryption helped previously because somehow fragmented skb's are not created if mac80211 encrypt frames, so buffer unmap bug of non-linear skbs was not triggered. Now since this bug is properly fixed by commit 7bd0650be63c ("mt76: dma: fix buffer unmap with non-linear skbs") , we can enable HW encryption back.

Move cc_active and cc_rx counters out of cc_lock since they are not modified in interrupt context. Grab cc_lock updating cur_cc_bss_rx in mt76_airtime_report and do not hold rx_lock in mt76_update_survey. Moreover grab mt76 mutex in mt76_get_survey before running mt76_update_survey.

2019-11-20mt76: mt76x0: eeprom: add support for MAC address from OFPawel Dembicki
mt76x0e driver only supports MAC addresses from calibration data eeprom. Many routers however do not have a valid stock address set in this field. This patch makes it possible to take a MAC address from OF (e.g. from mtd).

A rcu read locked section is not allowed to sleep, and the rcu lock here isn't actually necessary, because we're holding dev->mutex. Fixes an issue when the tid work item is still running while freeing a station or stopping the aggregation session Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-11-20mt76: do not use devm API for led classdevFelix Fietkau
With the devm API, the unregister happens after the device cleanup is done, after which the struct mt76_dev which contains the led_cdev has already been freed. This leads to a use-after-free bug that can crash the system. Signed-off-by: Felix Fietkau <nbd@nbd.name>
