[PATCH v4 3/7] phy: qcom-qusb2: Fix crash if nvmem cell not specified

by Manu Gautam

Driver currently crashes due to NULL pointer deference while updating PHY tune register if nvmem cell is NULL. Since, fused value for Tune1/2 register is optional, we'd rather bail out.

[PATCH v4 5/6] PCI: aardvark: Fix PCIe Max Read Request Size setting

[PATCH v4 4/6] PCI: aardvark: Use ISR1 instead of ISR0 interrupt in legacy irq mode

by Thomas Petazzoni

From: Victor Gu <xigu(a)marvell.com> The Aardvark has two interrupts sets: - first set is bit[23:16] of PCIe ISR 0 register(RD0074840h) - second set is bit[11:8] of PCIe ISR 1 register(RD0074848h) Only one set should be used, while another set should be masked. The second set, ISR1, is more advanced, the Legacy INT_X status bit is asserted once Assert_INTX message is received, and de-asserted after Deassert_INTX message is received. Therefore, it matches what the driver is currently doing in the ->irq_mask() and ->irq_unmask() functions. The ISR0 requires additional work to deassert the interrupt, which the driver doesn't do currently. This commit resolves a number of issues with legacy interrupts. This is part of fixing bug https://bugzilla.kernel.org/show_bug.cgi?id=196339, this commit was reported as the user to be important to get a Intel 7260 mini-PCIe WiFi card working.

[PATCH 1/1] Drivers: hv: vmbus: Fix ring buffer signaling

by kys＠exchange.microsoft.com

From: Michael Kelley <mhkelley(a)outlook.com> Fix bugs in signaling the Hyper-V host when freeing space in the host->guest ring buffer: 1. The interrupt_mask must not be used to determine whether to signal on the host->guest ring buffer 2. The ring buffer write_index must be read (via hv_get_bytes_to_write) *after* pending_send_sz is read in order to avoid a race condition 3. Comparisons with pending_send_sz must treat the "equals" case as not-enough-space 4. Don't signal if the pending_send_sz feature is not present. Older versions of Hyper-V that don't implement this feature will poll. Fixes: 03bad714a161 ("vmbus: more host signalling avoidance") Cc: Stable <stable(a)vger.kernel.org> # 4.14 and above Signed-off-by: Michael Kelley <mhkelley(a)outlook.com> Signed-off-by: K. Y.
