[PATCH] fdt_rw.c: Fix Unchecked return value error

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Fixed "Unchecked return value" error, by adding "(void)" in front of the
function call.

When Coverity Scan was ran on some of your code, a "Unchecked return value"
error was found at line 352 in fdt_rw.c. For similar errors that we received
for RTEMS, we created a macro that will assert the value returned and "use" the
return value with (void).
