Hello Markos
Sorry for the mess. I have already send a new patch for mips using the
_IO* macros
Just to put things a bit into context:
I did made the patch for serial and tested it only in x86. I wrongly
infer that the IOCTLS were defined for all the arches (sorry :S)
Then when the patch was applied on tty-next the build-bot throw some
errors for xtensa, that I fixed without using the IO_ macros
Then you came with your patch,
I realized that this could be wrong for mor arches, so I check the
rest and make patches for them.
Greg then pointed out that I should use _IO instead of numbers, so I
remade my patches using the _IO macros. I did not want to step into
your patch so I did not prepare a new one for mips
All the _IO patches (except mips) are now merged into tty-next.
Hopefully that one also get merged soon :)
Thanks for your help and sorry for any disturbance.
