Subject: [SPARC64] sunhv: Support SYSRQ properly.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=135066a21129760e44a51a7ef31d8c861f8ddace;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[SPARC64] sunhv: Support SYSRQ properly.

By calling uart_handle_break().  We'll still do the
"sun_do_break()" handling if the user gives two
breaks in a row.

We should probably do this in the other Sparc serial
drivers too.
