2021-02-01NFS: In nfs_readpage() only increment NFSIOS_READPAGES when read succeedsDave Wysochanski1-1/+1
There is a small inconsistency with nfs_readpage() vs nfs_readpages() with regards to NFSIOS_READPAGES. In readpage we unconditionally increment NFSIOS_READPAGES at the top, which means even if the read fails. In readpages, we increment NFSIOS_READPAGES at the bottom based on how many pages were successfully read. Change readpage to be consistent with readpages and so NFSIOS_READPAGES only reflects successful, non-fscache reads.

2021-02-01NFS: Clean up nfs_readpage() and nfs_readpages()Dave Wysochanski1-22/+23
In prep for the new fscache netfs API, refactor nfs_readpage() and nfs_readpages() for future patches. No functional change. Signed-off-by: Dave Wysochanski <dwysocha@redhat.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
2021-02-01nfs: Fix fall-through warnings for ClangGustavo A. R. Silva5-0/+7
In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple warnings by explicitly add multiple break/goto/return/fallthrough statements instead of just letting the code fall through to the next case.

2021-02-01SUNRPC: correct error code comment in xs_tcp_setup_socket()Calum Mackay1-4/+2
This comment was introduced by commit 6ea44adce915 ("SUNRPC: ensure correct error is reported by xs_tcp_setup_socket()"). I believe EIO was a typo at the time: it should have been EAGAIN. Subsequently, commit 0445f92c5d53 ("SUNRPC: Fix disconnection races") changed that to ENOTCONN. Rather than trying to keep the comment here in sync with the code in xprt_force_disconnect(), make the point in a non-specific way.

2021-01-31leds: rt8515: Add Richtek RT8515 LED driverLinus Walleij5-0/+421
This adds a driver for the Richtek RT8515 dual channel torch/flash white LED driver. This LED driver is found in some mobile phones from Samsung such as the GT-S7710 and GT-I8190. A V4L interface is added. We do not have a proper datasheet for the RT8515 but it turns out that RT9387A has a public datasheet and is essentially the same chip. We designed the driver in accordance with this datasheet. The day someone needs to drive a RT9387A this driver can probably easily be augmented to handle that chip too. Sakari Ailus, Pavel Machek and Andy Shevchenko helped significantly in getting this driver right.
