    Subject[PATCH 4.14 187/205] usb: gadget: udc: net2272: Fix bitwise and boolean operations
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Gustavo A. R. Silva <gustavo@embeddedor.com>

    commit 07c69f1148da7de3978686d3af9263325d9d60bd upstream.

    (!x & y) strikes again.

    Fix bitwise and boolean operations by enclosing the expression:

    intcsr & (1 << NET2272_PCI_IRQ)

    in parentheses, before applying the boolean operator '!'.

    Notice that this code has been there since 2011. So, it would
    be helpful if someone can double-check this.

    This issue was detected with the help of Coccinelle.
