One point is to have less places where we actually need tty pointer. The other is that low_latency is bound to buffer processing and buffers are now in tty_port. So it makes sense to move low_latency to tty_port too. Signed-off-by: NJiri Slaby <jslaby@suse.cz> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. tty_insert_flip_string this time.

probe routine could index into port[] with -ve index. The check in arc_uart_init_one() was too late.

CSR SiRFmarco's UART IP is same with SiRFprimaII except that it has two more uart ports. this patch makes the old driver support new SiRFmarco as well: 1. add .compatible = "sirf,marco-uart" to OF match table 2. add two ports in the port table 3. take spin_lock in isr to avoid the conflict of threads opening uart on CPU1 and isr running on CPU0. For 3, we did see some problems on SiRFmarco as SiRFmarco is a SMP SoC but the old SiRFprimaII is UP.

Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem makes memory leak. release function of dma-buf cannot be called because f_count of dma-buf increased by importing gem and gem ref count cannot be decrease because of exported dma-buf. So I add dma_buf_put() for imported gem come from its own gem into each drivers having prime_import and prime_export capabilities. With this, only gem ref count is increased if importing gem exported from gem of same driver.

After f65aad41("MIPS: Cavium: Add EDAC support."), when entering the "Device Drivers" toplevel menu in menuconfig, the suboptions behind EDAC appeared merged with the rest of the device drivers types. This was because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig bool which was defined after the menu definition. When pushing EDAC_SUPPORT up, before the menu definition, the variable is defined earlier and the above menuconfig artifact doesn't happen. Drop a useless menuconfig comment while at it.

vga-switcheroo with apple-gmux does not switch correctly on my system. The PCI configuration space is not restored correctly, resulting in MSI not working after switch. Only useful item in dmesg is: [ 33.922807] radeon 0000:01:00.0: Refused to change power state, currently in D3 I did some testing, dumping the difference in ms between first succesful switch from D3 to D0, and it seems that there is slightly more than 20 ms difference when the device is re-enabled through vga-switcheroo. So bump the re-enable d3 delay to 20 ms to handle this, which fixes msi not working on my system after switcheroo-ing. Default d3_delay value is PCI_PM_D3_WAIT, 10 ms.

If fimd is runtime suspended (by DPMS OFF), fimd_suspend does not call fimd_activate(false) and just returns. Similarily the check in fimd_resume should not resume if previously runtime_suspended. Instead the existing check does the opposite. So if fimd was not runtime suspended, suspend will turn off fimd but resume will not turn it on. This patch fixes this issue by reversing the condition.

When a channel fails to initialize, we release all ressources, including clocks. However, a XOR unit is not necessarily associated to a clock (some variants of Marvell SoCs have a clock for XOR units, some don't), so we shouldn't unconditionally be releasing the clock. Instead, just like we do in the mv_xor_remove() function, we should check if one clock was found before releasing it.

When mv_xor_channel_add() fails for one XOR channel, we jump to the err_channel_add label to clean up all previous channels that had been initialized correctly. Unfortunately, while handling this error condition, we were disposing the IRQ mapping before calling mv_xor_channel_remove() (which does the free_irq()), which is incorrect. Instead, do things properly in the reverse order of the initialization: first remove the XOR channel (so that free_irq() is done), and then dispose the IRQ mapping. This avoids ugly warnings when for some reason one of the XOR channel fails to initialize.
