2021-02-02amba: Make use of bus_type functionsUwe Kleine-König1-77/+81
Instead of assigning the needed functions for each driver separately do it only once in amba_bustype. Move the definition of the functions to their proper place among the other callbacks used there. Note that the bus's shutdown function might be called for unbound devices, too, so it needs additional guarding. This prepares getting rid of these callbacks in struct device_driver.

2021-02-02amba: Make the remove callback return voidUwe Kleine-König30-80/+34
All amba drivers return 0 in their remove callback. Together with the driver core ignoring the return value anyhow, it doesn't make sense to return a value here. Change the remove prototype to return void, which makes it explicit that returning an error value doesn't work as expected. This simplifies changing the core remove callback to return void, too.

2021-02-02amba: Fix resource leak for drivers without .removeUwe Kleine-König1-8/+12
Consider an amba driver with a .probe but without a .remove callback (e.g. pl061_gpio_driver). The function amba_probe() is called to bind a device and so dev_pm_domain_attach() and others are called. As there is no remove callback amba_remove() isn't called at unbind time however and so calling dev_pm_domain_detach() is missed and the pm domain keeps active. To fix this always use the core driver callbacks and handle missing amba callbacks there. For probe refuse registration as a driver without probe doesn't make sense.

2020-12-27proc mountinfo: make splice available againLinus Torvalds1-3/+6
Since commit 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") we've required that file operation structures explicitly enable splice support, rather than falling back to the default handlers. Most /proc files use the indirect 'struct proc_ops' to describe their file operations, and were fixed up to support splice earlier in commits 40be821d627c..b24c30c67863, but the mountinfo files interact with the VFS directly using their own 'struct file_operations' and got missed as a result. This adds the necessary support for splice to work for /proc/*/mountinfo and friends.

The fix is to move Tegra's link up handling to .start_link() function like other DWC drivers. Tegra is a bit more complicated than others as it re-inits the whole DWC controller to retry the link. With this, the initialization ordering is restored to match the prior sequence.

Add socket as a separate member so that it doesn't have to be packed into the int value. When the socket ID was larger than 8 bits the output appeared corrupted or incomplete. For example, here on ThunderX2 'perf stat' reports a socket of -1 and an invalid die number: ./perf stat -a --per-die The socket id number is too big. Performance counter stats for 'system wide': S-1-D255 128 687.99 msec cpu-clock # 57.240 CPUs utilized ... S36-D0 128 842.34 msec cpu-clock # 70.081 CPUs utilized ... And with --per-core there is an entry with an invalid core ID: ./perf stat record -a --per-core The socket id number is too big. Performance counter stats for 'system wide': S-1-D255-C65535 128 671.04 msec cpu-clock # 54.112 CPUs utilized ... S36-D0-C0 4 28.27 msec cpu-clock # 2.279 CPUs utilized ... This fixes the "Session topology" self test on ThunderX2. After this fix the output contains the correct socket and die IDs and no longer prints a warning about the size of the socket ID: ./perf stat --per-die -a Performance counter stats for 'system wide': S36-D0 128 169,869.39 msec cpu-clock # 127.501 CPUs utilized ...
