ath10k: Drop WARN_ON()s that always trigger during system resume

2019-05-05T12:42:41Z

commit 9e80ad37f6788ed52b89a3cfcd593e0aa69b216d upstream. ath10k_mac_vif_chan() always returns an error for the given vif during system-wide resume which reliably triggers two WARN_ON()s in ath10k_bss_info_changed() and they are not particularly useful in that code path, so drop them.

bnxt_en: Fix uninitialized variable usage in bnxt_rx_pkt().

2019-05-05T12:42:40Z

[ Upstream commit 0b397b17a4120cb80f7bf89eb30587b3dd9b0d1d ] In bnxt_rx_pkt(), if the driver encounters BD errors, it will recycle the buffers and jump to the end where the uninitailized variable "len" is referenced. Fix it by adding a new jump label that will skip the length update. This is the most correct fix since the length may not be valid when we get this type of error.

bnxt_en: Free short FW command HWRM memory in error path in bnxt_init_one()

bnxt_en: Improve multicast address setup logic.

2019-05-05T12:42:39Z

[ Upstream commit b4e30e8e7ea1d1e35ffd64ca46f7d9a7f227b4bf ] The driver builds a list of multicast addresses and sends it to the firmware when the driver's ndo_set_rx_mode() is called. In rare cases, the firmware can fail this call if internal resources to add multicast addresses are exhausted. In that case, we should try the call again by setting the ALL_MCAST flag which is more guaranteed to succeed. Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")

net: phy: marvell: Fix buffer overrun with stats counters

2019-05-05T12:42:38Z

[ Upstream commit fdfdf86720a34527f777cbe0d8599bf0528fa146 ] marvell_get_sset_count() returns how many statistics counters there are. If the PHY supports fibre, there are 3, otherwise two. marvell_get_strings() does not make this distinction, and always returns 3 strings. This then often results in writing past the end of the buffer for the strings. Fixes: 2170fef78a40 ("Marvell phy: add field to get errors from fiber link.")

net: macb: Add null check for PCLK and HCLK

2019-05-04T07:20:17Z

[ Upstream commit cd5afa91f078c0787be0a62b5ef90301c00b0271 ] 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.
