nvmem: core: Fix memleak in nvmem_register()

2022-10-24T07:56:46+00:00

commit bd1244561fa2a4531ded40dbf09c9599084f8b29 upstream.

dev_set_name will alloc memory for nvmem->dev.kobj.name in
nvmem_register, when nvmem_validate_keepouts failed, nvmem's
memory will be freed and return, but nobody will free memory
for nvmem->dev.kobj.name, there will be memleak, so moving
nvmem_validate_keepouts() after device_register() and let
the device core deal with cleaning name in error cases.

Fixes: de0534df9347 ("nvmem: core: fix error handling while validating keepout regions")

nvmem: sfp: Add support for TA 2.1 devices

2022-05-09T13:46:29+00:00

This adds support for Trust Architecture (TA) 2.1 devices to the SFP driver.
There are few differences between TA 2.1 and TA 3.0, especially for
read-only support, so just re-use the existing data.

nvmem: sfp: Use regmap

2022-05-09T13:46:29+00:00

This converts the SFP driver to use regmap. This will allow easily
supporting devices with different endians. We disallow byte-level
access, as regmap_bulk_read doesn't support it (and it's unclear what
the correct result would be when we have an endianness difference).

nvmem: qfprom: using pm_runtime_resume_and_get instead of pm_runtime_get_sync

2022-05-09T13:45:39+00:00

Using pm_runtime_resume_and_get is more appropriate
for simplifing code

nvmem: Add Apple eFuse driver

2022-05-09T13:44:21+00:00

Apple SoCs contain eFuses used to store factory-programmed data such
as calibration values for the PCIe or the Type-C PHY. They are organized
as 32bit values exposed as MMIO.

nvmem: brcm_nvram: find Device Tree nodes for NVMEM cells

2022-05-09T13:44:21+00:00

DT binding for Broadcom's NVRAM supports specifying NVMEM cells as NVMEM
device (provider) subnodes. Look for such subnodes when collecing NVMEM
cells. This allows NVMEM consumers to use NVRAM variables.

nvmem: core: support passing DT node in cell info

2022-05-09T13:44:21+00:00

Some hardware may have NVMEM cells described in Device Tree using
individual nodes. Let drivers pass such nodes to the NVMEM subsystem so
they can be later used by NVMEM consumers.

nvmem: sunplus-ocotp: drop useless probe confirmation

2022-04-24T15:15:15+00:00

Printing probe success is discouraged, because we can use tracing for
this purpose.  Remove useless print message after Sunplus OCOTP driver
probe.

nvmem: sunplus-ocotp: staticize sp_otp_v0

2022-04-24T15:15:14+00:00

The "sp_otp_v0" file scope variable is not used outside, so make it
static to fix warning:

  drivers/nvmem/sunplus-ocotp.c:74:29: sparse:
    sparse: symbol 'sp_otp_v0' was not declared. Should it be static?
