2020-01-20pwm: sun4i: Narrow scope of local variableUwe Kleine-König
The variable pval is only used in a single block in the function sun4i_pwm_calculate(). So declare it in a more local scope to simplify the function for humans and compilers. While at it also simplify assignment to pval. While the diffstat for this patch is negative for this patch I still thing the advantage of having a narrower scope is beneficial. In my compiler / .config setup (gcc 8.2.1, arm/imx_v6_v7_defconfig + COMPILE_TEST + PWM_SUN4I) this change doesn't result in any binary changes.

2019-12-09pwm: imx27: Unconditionally write state to hardwareThierry Reding
The i.MX driver currently uses a shortcut and doesn't write all of the state through to the hardware when the PWM is disabled. This causes an inconsistent state to be read back by consumers with the result of them malfunctioning. Fix this by always writing the full state through to the hardware registers so that the correct state can always be read back.

2019-12-09pwm: Read initial hardware state at request timeThierry Reding
Drivers that support reading the hardware state (using ->get_state()) may want to rely on per-PWM data to do so. Defer reading the hardware state for the first time until the PWM has been requested and after drivers have had a chance to allocate per-PWM data. Conceptually this is also a more natural place to read the hardware state because the PWM core doesn't need to know the hardware state of a PWM unless there is a user for it. This also ensures that the state is read everytime a user requests a PWM. If the PWM changes between users for some reason, the PWM core will reload the state from hardware and keep its copy of the state up-to-date.

Possibly most interesting is Trond's fixes for some callback races that were due to my incomplete understanding of rpc client shutdown. Unfortunately at the last minute I've started noticing a new intermittent failure to send callbacks. As the logic seems basically correct, I'm leaving Trond's patches in for now, and hope to find a fix in the next week so I don't have to revert those patches" * tag 'nfsd-5.5' of git://linux-nfs.org/~bfields/linux: (24 commits) nfsd: depend on CRYPTO_MD5 for legacy client tracking NFSD fixing possible null pointer derefering in copy offload nfsd: check for EBUSY from vfs_rmdir/vfs_unink. nfsd: Ensure CLONE persists data and metadata changes to the target file SUNRPC: Fix backchannel latency metrics nfsd: restore NFSv3 ACL support nfsd: v4 support requires CRYPTO_SHA256 nfsd: Fix cld_net->cn_tfm initialization lockd: remove __KERNEL__ ifdefs sunrpc: remove __KERNEL__ ifdefs race in exportfs_decode_fh() nfsd: Drop LIST_HEAD where the variable it declares is never used. nfsd: document callback_wq serialization of callback code nfsd: mark cb path down on unknown errors nfsd: Fix races between nfsd4_cb_release() and nfsd4_shutdown_callback() nfsd: minor 4.1 callback cleanup SUNRPC: Fix svcauth_gss_proxy_init() SUNRPC: Trace gssproxy upcall results sunrpc: fix crash when cache_head become valid before update nfsd: remove private bin2hex implementation ...

2019-12-07smb3: improve check for when we send the security descriptor context on createSteve French
We had cases in the previous patch where we were sending the security descriptor context on SMB3 open (file create) in cases when we hadn't mounted with with "modefromsid" mount option. Add check for that mount flag before calling ad_sd_context in open init. Signed-off-by: Steve French <stfrench@microsoft.com> Reviewed-by: Pavel Shilovsky <pshilov@microsoft.com>
