X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=53ee983378ff23e8f3ff95ecf99dea7c6c221900;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git Merge tag 'staging-3.17-rc1' of git://git./linux/kernel/git/gregkh/staging Pull staging driver updates from Greg KH: "Here's the big pull request for the staging driver tree for 3.17-rc1. Lots of things in here, over 2000 patches, but the best part is this: 1480 files changed, 39070 insertions(+), 254659 deletions(-) Thanks to the great work of Kristina Martšenko, 14 different staging drivers have been removed from the tree as they were obsolete and no one was willing to work on cleaning them up. Other than the driver removals, loads of cleanups are in here (comedi, lustre, etc.) as well as the usual IIO driver updates and additions. All of this has been in the linux-next tree for a while" * tag 'staging-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (2199 commits) staging: comedi: addi_apci_1564: remove diagnostic interrupt support code staging: comedi: addi_apci_1564: add subdevice to check diagnostic status staging: wlan-ng: coding style problem fix staging: wlan-ng: fixing coding style problems staging: comedi: ii_pci20kc: request and ioremap memory staging: lustre: bitwise vs logical typo staging: dgnc: Remove unneeded dgnc_trace.c and dgnc_trace.h staging: dgnc: rephrase comment staging: comedi: ni_tio: remove some dead code staging: rtl8723au: Fix static symbol sparse warning staging: rtl8723au: usb_dvobj_init(): Remove unused variable 'pdev_desc' staging: rtl8723au: Do not duplicate kernel provided USB macros staging: rtl8723au: Remove never set struct pwrctrl_priv.bHWPowerdown staging: rtl8723au: Remove two never set variables staging: rtl8723au: RSSI_test is never set staging:r8190: coding style: Fixed checkpatch reported Error staging:r8180: coding style: Fixed too long lines staging:r8180: coding style: Fixed commenting style staging: lustre: ptlrpc: lproc_ptlrpc.c - fix dereferenceing user space buffer staging: lustre: ldlm: ldlm_resource.c - fix dereferenceing user space buffer ... --- 53ee983378ff23e8f3ff95ecf99dea7c6c221900 diff --cc drivers/staging/android/sync.c index c9a0c2cdc81a,cd7b8f59b948..e7b2e0234196 --- a/drivers/staging/android/sync.c +++ b/drivers/staging/android/sync.c @@@ -549,14 -677,17 +549,13 @@@ static unsigned int sync_fence_poll(str poll_wait(file, &fence->wq, wait); - /* - * Make sure that reads to fence->status are ordered with the - * wait queue event triggering - */ - smp_rmb(); + status = atomic_read(&fence->status); - if (fence->status == 1) + if (!status) return POLLIN; - else if (fence->status < 0) + else if (status < 0) return POLLERR; - else - return 0; + return 0; } static long sync_fence_ioctl_wait(struct sync_fence *fence, unsigned long arg)
