platform/x86: ibm_rtl: remove unnecessary static in ibm_rtl_write()
Remove unnecessary static on local variable cmd_port_val. Such variable
is initialized before being used, on every execution path throughout
the function. The static has no benefit and, removing it reduces the
object file size.
This issue was detected using Coccinelle and the following semantic patch:
https://github.com/GustavoARSilva/coccinelle/blob/master/static/static_unused.cocci
In the following log you can see a difference in the object file size.
This log is the output of the size command, before and after the code
change:
