2019-12-05soc: aspeed: Fix snoop_file_poll()'s return typeLuc Van Oostenryck1-2/+2
snoop_file_poll() is defined as returning 'unsigned int' but the .poll method is declared as returning '__poll_t', a bitwise type. Fix this by using the proper return type and using the EPOLL constants instead of the POLL ones, as required for __poll_t.

2019-12-04gpio: pca953x: tighten up indentationAndy Shevchenko1-11/+11
There is no need to split some of the lines. However, improve the style of multi-line comment. On top of this there is no need to have double space.

2019-12-04vhost, kcov: collect coverage from vhost_workerAndrey Konovalov2-0/+7
Add kcov_remote_start()/kcov_remote_stop() annotations to the vhost_worker() function, which is responsible for processing vhost works. Since vhost_worker() threads are spawned per vhost device instance the common kcov handle is used for kcov_remote_start()/stop() annotations (see Documentation/dev-tools/kcov.rst for details). As the result kcov can now be used to collect coverage from vhost worker threads.

2019-12-04usb, kcov: collect coverage from hub_eventAndrey Konovalov1-0/+5
Add kcov_remote_start()/kcov_remote_stop() annotations to the hub_event() function, which is responsible for processing events on USB buses, in particular events that happen during USB device enumeration. Since hub_event() is run in a global background kernel thread (see Documentation/dev-tools/kcov.rst for details), each USB bus gets a unique global handle from the USB subsystem kcov handle range. As the result kcov can now be used to collect coverage from events that happen on a particular USB bus.

2019-12-04mm/vmstat: add helpers to get vmstat item names for each enum typeKonstantin Khlebnikov1-6/+3
Statistics in vmstat is combined from counters with different structure, but names for them are merged into one array. This patch adds trivial helpers to get name for each item: const char *zone_stat_name(enum zone_stat_item item); const char *numa_stat_name(enum numa_stat_item item); const char *node_stat_name(enum node_stat_item item); const char *writeback_stat_name(enum writeback_stat_item item); const char *vm_event_name(enum vm_event_item item); Names for enum writeback_stat_item are folded in the middle of vmstat_text so this patch moves declaration into header to calculate offset of following items. Also this patch reuses piece of node stat names for lru list names: const char *lru_list_name(enum lru_list lru); This returns common lru list names: "inactive_anon", "active_anon", "inactive_file", "active_file", "unevictable".

2019-12-04Input: synaptics-rmi4 - don't increment rmiaddr for SMBus transfersHans Verkuil1-2/+0
This increment of rmi_smbus in rmi_smb_read/write_block() causes garbage to be read/written. The first read of SMB_MAX_COUNT bytes is fine, but after that it is nonsense. Trial-and-error showed that by dropping the increment of rmiaddr everything is fine and the F54 function properly works. I tried a hack with rmi_smb_write_block() as well (writing to the same F54 touchpad data area, then reading it back), and that suggests that there too the rmiaddr increment has to be dropped. It makes sense that if it has to be dropped for read, then it has to be dropped for write as well. It looks like the initial work with F54 was done using i2c, not smbus, and it seems nobody ever tested F54 with smbus. The other functions all read/write less than SMB_MAX_COUNT as far as I can tell, so this issue was never noticed with non-F54 functions. With this change I can read out the touchpad data correctly on my Lenovo X1 Carbon 6th Gen laptop.

2019-12-04Input: synaptics-rmi4 - re-enable IRQs in f34v7_do_reflashLucas Stach1-0/+3
F34 is a bit special as it reinitializes the device and related driver structs during the firmware update. This clears the fn_irq_mask which will then prevent F34 from receiving further interrupts, leading to timeouts during the firmware update. Make sure to reinitialize the IRQ enables at the appropriate times. The issue is in F34 code, but the commit in the fixes tag exposed the issue, as before this commit things would work by accident.

2019-12-04net: ipv6_stub: use ip6_dst_lookup_flow instead of ip6_dst_lookupSabrina Dubroca5-17/+18
ipv6_stub uses the ip6_dst_lookup function to allow other modules to perform IPv6 lookups. However, this function skips the XFRM layer entirely. All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the ip_route_output_key and ip_route_output helpers) for their IPv4 lookups, which calls xfrm_lookup_route(). This patch fixes this inconsistent behavior by switching the stub to ip6_dst_lookup_flow, which also calls xfrm_lookup_route(). This requires some changes in all the callers, as these two functions take different arguments and have different return types.

cec4fa7511ef7a73eb635834e9d85b25a5b47a98 ("drm/omap: use refcount API to track the number of users of dma_addr") changed omap_gem.c to use refcounting API to track dma_addr uses. However, the driver only tracks the refcounts for non-contiguous buffers, and the patch didn't fully take this in account. After the patch, the driver always decreased refcount in omap_gem_unpin, instead of decreasing the refcount only for non-contiguous buffers. This leads to refcounting mismatch. As for the contiguous cases the refcount is never increased, fix this issue by returning from omap_gem_unpin if the buffer being unpinned is contiguous.
