A platform_driver does not need to set an owner, it will be populated by the
driver core.

Pull pwm changes from Thierry Reding:
"The majority of these changes are cleanups and fixes across all
drivers. Redundant error messages are removed and more PWM
controllers set the .can_sleep flag to signal that they can't be used
in atomic context.
Support is added for the Broadcom Kona family of SoCs and the Intel
LPSS driver can now probe PCI devices in addition to ACPI devices.
Upon shutdown, the pwm-backlight driver will now power off the
backlight. It also uses the new descriptor-based GPIO API for more
concise GPIO handling.
A large chunk of these changes also converts platforms to use the
lookup mechanism rather than relying on the global number space to
reference PWM devices. This is largely in preparation for more
unification and cleanups in future patches. Eventually it will allow
the legacy PWM API to be removed"

pwmchip_add() returns zero on success and a negative value on error,
so the condition of the check must be inverted.

The site-specific OOM messages are unnecessary, because they
duplicate the MM subsystem generic OOM message.

[email protected] email-id doesn't exist anymore as he has left the
company. Replace ST's id with [email protected].
It also updates .mailmap file to fix address for 'git shortlog'.

Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.
Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.
A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@
- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
e = devm_ioremap_resource(e1, res);
// </smpl>

Some drivers don't set the .owner fields of the struct device_driver or
struct pwm_ops, which causes the module usage count to become wrong.

A few drivers already annotate this properly. Make the same change for
all other OF supporting drivers.

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

Add support for PWM chips present on SPEAr platforms. These PWM
chips support 4 channel output with programmable duty cycle and
frequency.
More details on these PWM chips can be obtained from relevant
chapter of reference manual, present at following[1] location.
