adds checks on variables that are used to return values. If
the value is less than zero, this indicates that an error
occurred and hence a message is printed through dev_err.
Checks are made on negative values only since spi_* functions
return negative error codes.
The functions were found using the following script but the
aforementioned modification was what was carried out in the end:

identifier len,f;

-int len;

This patch removes a if condition which has a semicolon
after it. As the conditional check is redundant, the comment
before it is also changed. The following
coccinelle script was used to detect the pattern of a
semicolon after if.

if (...);@p

The following checkpatch warning was fixed:
Prefer [subsystem eg: netdev]_err([subsystem]dev

statements which followed a printk that did not end with a '\n'. The following
semantic patch was used to replace printk() with pr_err():

This patch removes the use of custom printk macros ERR and replace it
with dev_err, or pr_err in the following cases:
- if no appropriate struct device *dev field where found for dev_err.
- or dev could be null eg. "dev_err(udc->dev" not possible inside "if
(udc == null)"
