* mfd: tps65010: Fix init when the driver is built-inAaro Koskinen2016-03-09
| | | | | | | | | | | | | | | | | | tps65010 driver's initcall cannot succeed when the driver is built-in, because it expects that the I2C probe is completed at initcall time; this cannot happen as MFD is initialized before I2C. Also on systems where the chip is not present there is unnecessary 30 ms delay during the boot. Instead of waiting for probe to finish, just register the I2C device. If some boards need retry mechanism for startup glitches, that should be done in the actual probe function. Also delete the driver banner message. The patch allows to use tps65010 again with OMAP1 (where it's required to be built-in) and enables e.g. USB and LED functionality on OMAP5912 OSK.

This patch follows the example of mfd/wm831x and splits it into an interface independent core, and an i2c specific glue layer. MFD_AXP20X and the new MFD_AXP20X_I2C are changed to tristate symbols, allowing the driver to be built as modules. Whitespace and other style errors in the moved i2c specific code have been fixed.

The latter API is only used by this driver, although this driver only allocates one clk to add anyway. Furthermore, this driver allocates the clk_lookup structure with devm, but clkdev_drop() will free that structure when passed, leading to a double free when this driver is removed.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current acm driver, the bulk-in callback function ignores the URBs unlinked in usb core. This causes unexpected data loss in some cases. For example, runtime suspend entry will unlinked all urbs and set urb->status to -ENOENT even those urbs might have data not processed yet. Hence, data loss occurs. This patch lets bulk-in callback function handle unlinked urbs to avoid data loss.

The LPSS UART block is pretty much same as used on Intel Baytrail so we can reuse the existing Baytrail setup code. Add both Broadwell LPSS UART ports to the list of supported devices.

| * | staging/speakup: Use tty_ldisc_ref() for paste kworkerPeter Hurley2016-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the function documentation for tty_ldisc_ref_wait() notes, it is only callable from a tty file_operations routine; otherwise there is no guarantee the ref won't be NULL. The key difference with the VT's paste_selection() is that is an ioctl, where __speakup_paste_selection() is completely async kworker, kicked off from interrupt context.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although n_tty_check_unthrottle() has a valid ldisc reference (since the tty core gets the ldisc ref in tty_read() before calling the line discipline read() method), it does not have a valid ldisc reference to the "other" pty of a pty pair. Since getting an ldisc reference for tty->link essentially open-codes tty_wakeup(), just replace with the equivalent tty_wakeup().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ioctl(TIOCGETD) retrieves the line discipline id directly from the ldisc because the line discipline id (c_line) in termios is untrustworthy; userspace may have set termios via ioctl(TCSETS*) without actually changing the line discipline via ioctl(TIOCSETD). However, directly accessing the current ldisc via tty->ldisc is unsafe; the ldisc ptr dereferenced may be stale if the line discipline is changing via ioctl(TIOCSETD) or hangup. Wait for the line discipline reference (just like read() or write()) to retrieve the "current" line discipline id.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A small window exists where a tty reopen will observe the tty just prior to imminent teardown (tty->count == 0); in this case, open() returns EIO to userspace. Instead, retry the open after checking for signals and yielding; this interruptible retry loop allows teardown to commence and initialize a new tty on retry. Never retry the BSD master pty reopen; there is no guarantee the pty pair teardown is imminent since the slave file descriptors may remain open indefinitely.
