[PATCH v2 1/2] nfc: mrvl: remove useless "continue" at end of loop

From: Krzysztof Kozlowski <hidden>
Date: 2021-06-02 11:20:35

The "continue" statement at the end of a for loop does not have an
effect.  Entire loop contents can be slightly simplified to increase
code readability.  No functional change.

Changes since v1:
1. Make it if-else-if as Joe suggested.

[PATCH v2 2/2] nfc: mrvl: reduce the scope of local variables

From: Krzysztof Kozlowski <hidden>
Date: 2021-06-02 11:20:39

In two places the 'ep_desc' and 'skb' local variables are used only
within if() or for() block, so they scope can be reduced which makes the
entire code slightly easier to follow.  No functional change.
