eni_init_one() misses to call pci_disable_device() in an error path.
Jump to err_disable to fix it.

When make_rate() fails, vcc should be freed just
like other error paths in fs_open().

[ Upstream commit 51875dad43b44241b46a569493f1e4bfa0386d86 ]

atmtcp_remove_persistent() invokes atm_dev_lookup(), which returns a
reference of atm_dev with increased refcount or NULL if fails.

The refcount leaks issues occur in two error handling paths. If
dev_data->persist is zero or PRIV(dev)->vcc isn't NULL, the function
returns 0 without decreasing the refcount kept by a local variable,
resulting in refcount leaks.

Fix the issue by adding atm_dev_put() before returning 0 both when
dev_data->persist is zero or PRIV(dev)->vcc isn't NULL.

In fore200e_send and fore200e_close, the pointers from the arguments
are dereferenced in the variable declaration block and then checked
for NULL. The patch fixes these issues by avoiding NULL pointer
dereferences.

With -O3, gcc has found an actual unintialized variable stored
into an mmio register in two instances:

drivers/atm/eni.c: In function 'discard':
drivers/atm/eni.c:465:13: error: 'dma[1]' is used uninitialized in this function [-Werror=uninitialized]
   writel(dma[i*2+1],eni_dev->rx_dma+dma_wr*8+4);
             ^
drivers/atm/eni.c:465:13: error: 'dma[3]' is used uninitialized in this function [-Werror=uninitialized]

Change the code to always write zeroes instead.

[ Upstream commit fa865ba183d61c1ec8cbcab8573159c3b72b89a4 ]

In fs_open(), 'vcc' is allocated through kmalloc() and assigned to
'atm_vcc->dev_data.' In the following execution, if an error occurs, e.g.,
there is no more free channel, an error code EBUSY or ENOMEM will be
returned. However, 'vcc' is not deallocated, leading to memory leaks. Note
that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated
in fs_close(). But, if fs_open() fails, there is no guarantee that
fs_close() will be invoked.

To fix this issue, deallocate 'vcc' before the error code is returned.
