[PATCH v8 10/14] spi: mxic: Fix the transmit path

by Miquel Raynal

By working with external hardware ECC engines, we figured out that Under certain circumstances, it is needed for the SPI controller to check INT_TX_EMPTY and INT_RX_NOT_EMPTY in both receive and transmit path (not only in the receive path). The delay penalty being negligible, move this code in the common path.

[PATCH v2 1/3] ALSA: hda/tegra: Fix Tegra194 HDA reset failure

by Sameer Pujar

HDA regression is recently reported on Tegra194 based platforms. This happens because "hda2codec_2x" reset does not really exist in Tegra194 and it causes probe failure. All the HDA based audio tests fail at the moment. This underlying issue is exposed by commit c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP response") which now checks return code of BPMP command response. Fix this issue by skipping unavailable reset on Tegra194.

[PATCH 1/6] Bluetooth: add quirk disabling LE Read Transmit Power

by Aditya Garg

From: Aditya Garg <redecorating(a)protonmail.com> Some devices have a bug causing them to not work if they query LE tx power on startup. Thus we add a quirk in order to not query it and default min/max tx power values to HCI_TX_POWER_INVALID.
