      media: sir_ir: remove unnecessary static in sir_interrupt() · 6efa0943
      Gustavo A. R. Silva authored
      Remove unnecessary static on local variable delt.
      Such variable is initialized before being used,
      on every execution path throughout the function.
      The static has no benefit and, removing it reduces
      the code size.
      
      This issue was detected using Coccinelle and the following semantic patch:
      
      @bad exists@
      position p;
      identifier x;
      type T;
      @@
      
      static T x@p;
      ...
      x = <+...x...+>
      
      @@
      identifier x;
      expression e;
      type T;
      position p != bad.p;
      @@
      
      -static
       T x@p;
       ... when != x
           when strict
      ?x = e;
      
      In the following log you can see the difference in the code size. Also,
      there is a significant difference in the bss segment. This log is the
      output of the size command, before and after the code change:
      
      before:
         text    data     bss     dec     hex filename
         5009    3456     576    9041    2351 drivers/media/rc/sir_ir.o
      
      after:
         text    data     bss     dec     hex filename
         4988    3400     512    8900    22c4 drivers/media/rc/sir_ir.o

      staging: lirc: remove sa1100 support · c72374ff
      Arnd Bergmann authored
      The LIRC support for sa1100 appears to have never worked
      because it relies on header files that have never been
      present in git history. Actually trying to build the
      driver on an ARM sa1100 kernel fails, so let's just remove
      the broken support.
