kdb: make "mdr" command repeat

2018-05-30T05:47:45Z

[ Upstream commit 1e0ce03bf142454f38a5fc050bf4fd698d2d36d8 ] The "mdr" command should repeat (continue) when only Enter/Return is pressed, so make it do so.

regulator: of: Add a missing 'of_node_put()' in an error handling path of 'of_regulator_match()'

[ Upstream commit 30966861a7a2051457be8c49466887d78cc47e97 ] If an unlikely failure in 'of_get_regulator_init_data()' occurs, we must release the reference on the current 'child' node before returning.

scsi: lpfc: Fix frequency of Release WQE CQEs

2018-05-30T05:47:45Z

[ Upstream commit 04673e38f56b30cd39b1fa0f386137d818b17781 ] The driver controls when the hardware sends completions that communicate consumption of elements from the WQ. This is done by setting a WQEC bit on a WQE. The current driver sets it on every Nth WQE posting. However, the driver isn't clearing the bit if the WQE is reused. Thus, if the queue depth isn't evenly divisible by N, with enough time, it can be set on every element, creating a lot of overhead and risking CQ full conditions. Correct by clearing the bit when not setting it on an Nth element. Signed-off-by: Dick Kennedy Signed-off-by: James Smart Reviewed-by: Hannes Reinecke Signed-off-by: Martin K.

scsi: lpfc: Fix soft lockup in lpfc worker thread during LIP testing

2018-05-30T05:47:45Z

[ Upstream commit 161df4f09987ae2e9f0f97f0b38eee298b4a39ff ] During link bounce testing in a point-to-point topology, the host may enter a soft lockup on the lpfc_worker thread: Call Trace: lpfc_work_done+0x1f3/0x1390 [lpfc] lpfc_do_work+0x16f/0x180 [lpfc] kthread+0xc7/0xe0 ret_from_fork+0x3f/0x70 The driver was simultaneously setting a combination of flags that caused lpfc_do_work()to effectively spin between slow path work and new event data, causing the lockup. Ensure in the typical wq completions, that new event data flags are set if the slow path flag is running. The slow path will eventually reschedule the wq handling.

audit: return on memory error to avoid null pointer dereference

clk: samsung: exynos3250: Fix PLL rates

2018-05-30T05:47:44Z

[ Upstream commit a8321e7887410a2b2e80ab89d1ef7b30562658ea ] Rates declared in PLL rate tables should match exactly rates calculated from PLL coefficients. If that is not the case, rate of the PLL's child clock might be set not as expected. For instance, if in the PLL rates table we have a 393216000 Hz entry and the real value as returned by the PLL's recalc_rate callback is 393216003, after setting PLL's clk rate to 393216000 clk_get_rate will return 393216003. If we now attempt to set rate of a PLL's child divider clock to 393216000/2 its rate will be 131072001, rather than 196608000. That is, the divider will be set to 3 instead of 2, because 393216003/2 is greater than 196608000. To fix this issue declared rates are changed to exactly match rates generated by the PLL, as calculated from the P, M, S, K coefficients. In this patch an erroneous P value for 74176002 output frequency is also corrected.
