usb: gadget: udc: net2272: Fix bitwise and boolean operations
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.
