-Subject: [PATCH 159/226] staging: fsl-mc: bus: Eliminate double function call
-
-A call to irq_find_matching_host was already made and the result
-has been stored in mc_msi_domain. mc_msi_domain is again reassigned
-using the same function call which is redundant.
-
-irq_find_matching_host returns/locates a domain for a given fwnode.
-The domain is identified using device node and bus_token(if several
-domains have same device node but different purposes they can be
-distinguished using bus-specific token).
-http://www.bricktou.com/include/linux/irqdomain_irq_find_matching_host_en.html
-
-Also, of_property_read_bool finds and reads a boolean from a property
-device node from which the property value is to be read. It doesn't
-alter the device node.
-http://lists.infradead.org/pipermail/linux-arm-kernel/2012-February/083698.html
-
-Since, both  the function calls have the same device node and bus_token,
-the return values shall be the same. Hence, the second call has been
-removed.
-
-This was done using Coccinelle:
-
-@r@
-idexpression *x;
-identifier f;
-position p1,p2;
-@@
-
-x@p1 = f(...)
-... when != x
-(
-x@p2 = f(...)
-)
-
-@script:python@
-p1 << r.p1;
-p2 << r.p2;
-@@
-
-if (p1[0].line == p2[0].line):
-  cocci.include_match(False)
-
-@@
-idexpression *x;
-identifier f;
-position r.p1,r.p2;
-@@
-
-*x@p1 = f(...)
-...
-*x@p2 = f(...)
