mm: use vmf->address instead of of vmf->virtual_address

2016-12-15T00:04:09+00:00

Every single user of vmf->virtual_address typed that entry to unsigned
long before doing anything with it so the type of virtual_address does
not really provide us any additional safety.  Just use masked
vmf->address which already has the appropriate type.

staging: android: ion: Fix error handling in ion_query_heaps()

2016-10-24T13:36:15+00:00

If the copy_to_user() fails we should unlock and return directly without
updating "cnt".  Also the return value should be -EFAULT instead of the
number of bytes remaining.

The removed parentheses are unnecessary and don't add readability.

Staging: android: ion: constify dma_buf_ops structure

2016-10-17T07:46:58+00:00

The dma_buf_ops structure is stored in the ops field of a
dma_buf_export_info structure and also used as a condition inside the
if() statement. The if condition does not modify its value and the
ops field is of type const struct *dma_buf_ops, so dma_buf_ops
structures having this property can be declared as const.

staging: android/ion: testing the wrong variable

2016-10-17T07:14:55+00:00

We're testing "pdev" but we intended to test "heap_pdev".  This is a
static checker fix and it's unlikely that anyone is affected by this
bug.
