[PATCH] usb: dwc3: gadget: Fix logical condition

by Tejas Joglekar

This patch corrects the condition to kick the transfer without giving back the requests when either request has remaining data or when there are pending SGs. The && check was introduced during spliting up the dwc3_gadget_ep_cleanup_completed_requests() function.

[PATCH] jffs2: Fix integer underflow in jffs2_rtime_compress

[PATCH] iwlwifi: mvm: don't send the IWL_MVM_RXQ_NSSN_SYNC notif to Rx queues

by Emmanuel Grumbach

The purpose of this was to keep all the queues updated with the Rx sequence numbers because unlikely yet possible situations where queues can't understand if a specific packet needs to be dropped or not. Unfortunately, it was reported that this caused issues in our DMA engine. We don't fully understand how this is related, but this is being currently debugged. For now, just don't send this notification to the Rx queues. This de-facto reverts my commit 3c514bf831ac12356b695ff054bef641b9e99593: iwlwifi: mvm: add a loose synchronization of the NSSN across Rx queues This issue was reported here: https://bugzilla.kernel.org/show_bug.cgi?id=204873 https://bugzilla.kernel.org/show_bug.cgi?id=205001 and others maybe.

[PATCH 2/3] genirq/irqdomain: Re-check mapping after associate in irq_create_mapping()

by Sverdlin, Alexander (Nokia - DE/Ulm)

From: Alexander Sverdlin <alexander.sverdlin(a)nokia.com> If two irq_create_mapping() calls perform a mapping of the same hwirq on two CPU cores in parallel they both will get 0 from irq_find_mapping(), both will allocate unique virq using irq_domain_alloc_descs() and both will finally irq_domain_associate() it. Giving different virq numbers to their callers. In practice the first caller is usually an interrupt controller driver and the seconds is some device requesting the interrupt providede by the above interrupt controller. In this case either the interrupt controller driver configures virq which is not the one being "associated" with hwirq, or the "slave" device requests the virq which is never being triggered.

[PATCH][STABLE backport 4.4] dmaengine: qcom: bam_dma: Fix resource leak

by Jeffrey Hugo

Commit 7667819385457b4aeb5fac94f67f52ab52cc10d5 upstream. bam_dma_terminate_all() will leak resources if any of the transactions are committed to the hardware (present in the desc fifo), and not complete. Since bam_dma_terminate_all() does not cause the hardware to be updated, the hardware will still operate on any previously committed transactions. This can cause memory corruption if the memory for the transaction has been reassigned, and will cause a sync issue between the BAM and its client(s). Fix this by properly updating the hardware in bam_dma_terminate_all().

[PATCH v3] power/supply: ingenic-battery: Don't change scale if there's only one

by Paul Cercueil

The ADC in the JZ4740 can work either in high-precision mode with a 2.5V range, or in low-precision mode with a 7.5V range. The code in place in this driver will select the proper scale according to the maximum voltage of the battery. The JZ4770 however only has one mode, with a 6.6V range. If only one scale is available, there's no need to change it (and nothing to change it to), and trying to do so will fail with -EINVAL.
