Hi,

I think the subject should describe the problem rather than how the problem
got there. Perhaps something like this:


  Subject: [PATCH] soc: ti: pruss: remove misplaced semicolon from pruss_cfg_xfr_enable

And I think it would be best if there was a patch description. The problem
is self-evident, but I think it should at least be stated. And some
information on how this problem manifests wouldn't go astray. Something
like this.

  Remove misplaced colon in inline variant of pruss_cfg_xfr_enable()
  which results in a syntax error when the code is compiled without
  CONFIG_TI_PRUSS.

  Found using ...

FWIIW, I believe that in order for compilation (of
drivers/net/ethernet/ti/icssg/icssg_prueth_sr1.o) to work without
CONFIG_TI_PRUSS the following is also needed. Because there is a mismatch
between the return type of these functions and the type of the values
returned.
