silence-serial-console-gta01.patch
This patch ensures that no console data will go the UART while
the GSM mux is switched to the GSM. This is necessary despite
the code that disables the console due to the fact that the
console resumes before the neo1973_pm_gsm driver, and consoles
always resume in the "on" state.
