commit ded2f295a36d17838fe97e80d7b6ea83381474f8 upstream.

Commit bbb63c514a3464342967237a51a21ea8f61ab951 (drivers:tty:fix up
ENOIOCTLCMD error handling) changed the default return value from tty
ioctl to be ENOTTY and not EINVAL. This is appropriate.

But in case of TIOCGPTN for the old BSD ptys glibc started failing
because it expects EINVAL to be returned. Only then it continues to
obtain the pts name the other way around.

So fix this case by explicit return of EINVAL in this case.

mxs: uart: fix setting RTS from software

commit a6833214cfc6fa8a7c59426af77794cc190c6cfc upstream.

With the patch "serial: mxs-auart: fix the wrong RTS hardware flow control" the
mainline mxs-uart driver now sets RTSEN only when hardware flow control is
enabled via software. It is not possible any longer to set RTS manually via
software. However, the manual modification is a valid operation.
Regain the possibility to set RTS via software and only set RTSEN when hardware
flow control is explicitly enabled via settermios cflag CRTSCTS.

staging: vt6656: Fix inconsistent structure packing

commit 1ee4c55fc9620451b2a825d793042a7e0775391b upstream.

vt6656 has several headers that use the #pragma pack(1) directive to
enable structure packing, but never disable it.  The layout of
structures defined in other headers can then depend on which order the
various headers are included in, breaking the One Definition Rule.

In practice this resulted in crashes on x86_64 until the order of header
inclusion was changed for some files in commit 11d404cb56ecd ('staging:
vt6656: fix headers and add cfg80211.').  But we need a proper fix that
won't be affected by future changes to the order of inclusion.

This removes the #pragma pack(1) directives and adds __packed to the
structure definitions for which packing appears to have been intended.

Commit 2e254212 broke listing of available network names, since it

8250/16?50: Add support for Broadcom TruManage redirected serial port

commit ebebd49a8eab5e9aa1b1f8f1614ccc3c2120f886 upstream.

Add support for the UART device present in Broadcom TruManage capable
NetXtreme chips (ie: 5761m 5762, and 5725).

This implementation has a hidden transmit FIFO, so running in single-byte
interrupt mode results in too many interrupts.  The UART_CAP_HFIFO
capability was added to track this.  It continues to reload the THR as long
as the THRE and TSRE bits are set in the LSR up to a specified limit (1024
is used here).
