If the probe is deferred, -EPROBE_DEFER should be returned, not
+EPROBE_DEFER.

Use devm_clk_get_[optional_]enabled() instead of hand writing it.
It saves some LoC.

Code could be simplified even further and xor_dev->reg_clk and xor_dev->clk
could be removed as well.

I had thought I had a Smatch check for this but apparently not...  I
have attached a check plus the error messages.  Some places use positive
error codes intentionally.

regards,
dan carpenter

Heh.  Looking through the Smatch results, I don't think this actually
affects runtime because driver_probe_device() checks for both positive
and negatives.  People shouldn't be returning positives, of course, but
it appears there is a work around for bugs built in already.

A bunch of false positives could be silenced by changing the assign
and return hooks to check for unsigned types:

static void match_assign(struct expression *expr)
{
        if (expr_unsigned(expr->left))
                return;
        warn_on_positive_error(expr->right);
}

static void match_return(struct expression *expr)
{
        struct symbol *type;

        type = cur_func_return_type();
        if (type_unsigned(type))
                return;

        warn_on_positive_error(expr);
}

regards,
dan carpenter

Correct, but weird.

I've tried to look at the history of [1], but couldn't find any rational 
for it.

Apparently it was already in the v1 of the serie. [2]
