[ Upstream commit 0d83539092ddb1ab79b4d65bccb866bf07ea2ccd ]
Commit 75f0aef622 ("uio: fix memory leak") has fixed up some
memory leaks during the failure paths of the addition of uio
attributes, but still is not correct entirely. A kobject_uevent()
failure still needs a kobject_put() and the kobject container
structure allocation failure before the kobject_init() doesn't
need a kobject_put(). Fix this properly.

If guard_memory dtsi property is set, then the shared memory
region will be guarded by SZ_4K at the start and at the end.
This is needed to overcome the XPU limitation on few MSM HW,
so as to make this memory not contiguous with other allocations
that may possibly happen from other clients in the system.

The variable debug_buffer is a global variable which is allocated
and free'd when open/close is called on debugfs file -
"/sys/kernel/debug/rmt_storage/info". The current code doesn't
have locks to handle concurrent accesses to the above file.
This results into use after free issue when debug_buffer is
accessed by two threads at the same time. Fix this by adding
a mutex lock to protect this global variable.

The variable i contains a total number of resources (including
IORESOURCE_IRQ). However, we want the dmem_region_start to point
after the last resource of type IORESOURCE_MEM. The original behaviour
leads (very likely) to skipping several UIO mapping regions and makes
them useless. Fix this by computing dmem_region_start from the uiomem
which points to the last used UIO mapping.

UIO base driver should only free_irq that it has requested.
UIO supports drivers without interrupts (irq == 0) or custom handlers.
This fixes warnings like:
WARNING: CPU: 1 PID: 5478 at kernel/irq/manage.c:1244 __free_irq+0xa9/0x1e0()
Trying to free already-free IRQ 0

Separate irq request/free from the device lifecycle.
After device unregister the parent module can call pci_disable_msi.
>From the PCI MSI how to:
"Before calling this function, a device driver must always call free_irq()
on any interrupt for which it previously called request_irq().
Failure to do so results in a BUG_ON(), leaving the device with
MSI enabled and thus leaking its vector."
So we need to separately free the irq at unregister to allow the device
to be kept around in the case of it still having open FDs.

the vma range size is always page size aligned in mmap, while the
real io space range may not be page aligned, thus leading to range
check failure in the uio_mmap_physical().
for example, in a case of io range size "mem->size == 1KB", and we
have (vma->vm_end - vma->vm_start) == 4KB, due to "len" is aligned
to page size in do_mmap_pgoff().
now fix this issue by align mem->size to page size in the check.

When platform_get_irq() is failed after "priv" allocated,
it need to free "priv". But the label of bad0 doesn't try
to free about "priv". So this patch changes that lable to "bad1".
But "bad1" has pm_runtime_disable() call, this function should
be called when uio_register_device() is failed. So it is moved
into handling error for uio_register_device().

Commit e6789cd3df (uio: Simplify uio error
path by using devres functions) converted uio to use devm_request_irq().
This introduced a change in behaviour since the IRQ is associated with
the parent device instead of the created UIO device. The IRQ will remain
active after uio_unregister_device() is called, and some drivers will
crash because of this. The patch fixes this.

In commit 7314e613d5 ("Fix a few incorrectly checked
[io_]remap_pfn_range() calls") the uio driver started more properly
checking the passed-in user mapping arguments against the size of the
actual uio driver data.
That in turn exposed that some driver authors apparently didn't realize
that mmap can only work on a page granularity, and had tried to use it
with smaller mappings, with the new size check catching that out.
So since it's not just the user mmap() arguments that can be confused,
make the uio mmap code also verify that the uio driver has the memory
allocated at page boundaries in order for mmap to work. If the device
memory isn't properly aligned, we return
[ENODEV]
The fildes argument refers to a file whose type is not supported by mmap().
as per the open group documentation on mmap.

Most architectures define virt_to_page() as a macro that casts its
argument such that an argument of type unsigned long will be accepted
without complaint. However, the proper type is void *, and passing
unsigned long results in a warning on MIPS.
