2019-03-21net: hns3: fix for not calculating tx bd num correctlyYunsheng Lin
When there is only one byte in a frag, the current calculation using "(size + HNS3_MAX_BD_SIZE - 1) >> HNS3_MAX_BD_SIZE_OFFSET" will return zero, because HNS3_MAX_BD_SIZE is 65535 and HNS3_MAX_BD_SIZE_OFFSET is 16. So it will cause tx error when a frag's size is one byte. This patch fixes it by using DIV_ROUND_UP.

2019-03-21net: macb: Add null check for PCLK and HCLKHarini Katakam
Both PCLK and HCLK are "required" clocks according to macb devicetree documentation. There is a chance that devm_clk_get doesn't return a negative error but just a NULL clock structure instead. In such a case the driver proceeds as usual and uses pclk value 0 to calculate MDC divisor which is incorrect. Hence fix the same in clock initialization.

2019-03-21drm/amd/display: Only allow VRR when vrefresh is within supported rangeNicholas Kazlauskas
[Why] Black screens or artifacting can occur when enabling FreeSync outside of the supported range of the monitor. This can happen since the supported range isn't always the min/max vrefresh range available for the monitor. [How] There was previously a fix that prevented this from happening in the low range but it didn't cover the upper range. Expand the condition to include both.

2019-03-21mmc: alcor: fix DMA readsDaniel Drake
Setting max_blk_count to 1 here was causing the mmc block layer to always use the MMC_READ_SINGLE_BLOCK command here, which the driver does not DMA-accelerate. Drop the max_blk_ settings here. The mmc host defaults suffice, along with the max_segs and max_seg_size settings, which I have now documented in more detail. Now each MMC command reads 4 512-byte blocks, using DMA instead of PIO. On my SD card, this increases read performance (measured with dd) from 167kb/sec to 4.6mb/sec.

2019-03-21mmc: sdhci-omap: Set caps2 to indicate no physical write protect pinKishon Vijay Abraham I
After commit 6d5cd068ee59fba ("mmc: sdhci: use WP GPIO in sdhci_check_ro()") and commit 39ee32ce486756f ("mmc: sdhci-omap: drop ->get_ro() implementation"), sdhci-omap relied on SDHCI_PRESENT_STATE to check if the card is read-only, if wp-gpios is not populated in device tree. However SDHCI_PRESENT_STATE in sdhci-omap does not have correct read-only state. sdhci-omap can be used by platforms with both micro SD slot and standard SD slot with physical write protect pin (using GPIO). Set caps2 to MMC_CAP2_NO_WRITE_PROTECT based on if wp-gpios property is populated or not. This fix is required since existing device-tree node doesn't have "disable-wp" property and to preserve old-dt compatibility.

2019-03-21staging: rtlwifi: Fix potential NULL pointer dereference of kzallocAditya Pakki
phydm.internal is allocated using kzalloc which is used multiple times without a check for NULL pointer. This patch avoids such a scenario by returning 0, consistent with the failure case.

2019-03-21staging: rtl8712: uninitialized memory in read_bbreg_hdl()Dan Carpenter
Colin King reported a bug in read_bbreg_hdl(): memcpy(pcmd->rsp, (u8 *)&val, pcmd->rspsz); The problem is that "val" is uninitialized. This code is obviously not useful, but so far as I can tell "pcmd->cmdcode" is never GEN_CMD_CODE(_Read_BBREG) so it's not harmful either. For now the easiest fix is to just call r8712_free_cmd_obj() and return.

2019-03-21staging: rtlwifi: rtl8822b: fix to avoid potential NULL pointer dereferenceAditya Pakki
skb allocated via dev_alloc_skb can fail and return a NULL pointer. This patch avoids such a scenario and returns, consistent with other invocations.

hwxmits is allocated via kcalloc and not checked for failure before its dereference. The patch fixes this problem by returning error upstream in rtl8723bs, rtl8188eu.
