It is annotated as __devinitconst. Despite the annotation is useless
in most cases, const keyword is misssing there. So we are placing

In case alloc_tty_struct fails in pty_common_install, we pass NULL to
free_tty_struct. This is invalid as the function is not ready to cope
with that. And even if it was, it is not nice to do that anyway.

This trivial patch adds a short description for SERIAL_CLPS711X Kconfig
entry, removes excess dependence on the ARM-platform (this is done
globally for the platform), allows the driver to be compiled by default
and removes unnecessary description about GRUB and LILO, because these
bootloaders do not supported this platform.

When PARMRK is set and large transfers of characters that will get
marked are being received, n_tty could drop data silently (i.e.
without reporting any error to the client). This is because
characters have the potential to take up to three bytes in the line
discipline (when they get marked with parity or framing errors), but
the amount of free space reported to tty_buffer flush_to_ldisc (via
tty->receive_room) is based on the pre-marked data size.
With this patch, the n_tty layer will no longer assume that each byte
will only take up one byte in the line discipline. Instead, it will
make an overly conservative estimate that each byte will take up
three bytes in the line discipline when PARMRK is set.

The brcmsmac driver requests firmware but doesn't document the
dependency. This means that software that analyzes the modules to
determine if firmware is needed won't detect it.
Specifically, (at least) openSUSE won't install the kernel-firmware
package if no hardware requires it.
This patch adds the MODULE_FIRMWARE directives.
