There is no public one due to kernel.org being down. Does your patch apply to linux-next?

It does not, and I see why now. Looks like the internal tree is not in sync after all. I will post a V2 shortly.

The ePAPR hypervisor byte channel console driver only supports one byte channel as a console, and the byte channel handle is stored in a global variable. It doesn't make any sense to pass that handle as a parameter to the console functions, since these functions already have access to the global variable. This change also fixes this compilation warning on a 64-bit kernel: CC drivers/tty/ehv_bytechan.o drivers/tty/ehv_bytechan.c: In function 'ehv_bc_console_write': drivers/tty/ehv_bytechan.c:289:24: warning: cast from pointer to integer of different size drivers/tty/ehv_bytechan.c: In function 'ehv_bc_console_init': drivers/tty/ehv_bytechan.c:355:24: warning: cast to pointer from integer of different size This warning is because the driver is converting the integer byte channel handle to/from the void* 'data' field of struct console. Rather than fix the warning, we just eliminate the code altogether.
