2021-02-01ARM: 9048/1: sa1111: make sa1111 bus's remove callback return voidUwe Kleine-König3-8/+3
The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. To simplify the quest to make this function return void, let struct sa1111_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.

Commit c9a3c4e637ac ("mfd: ab8500-debugfs: Remove extraneous curly brace") removed a left-over curly brace that caused build failures, but Joe Perches points out that the subsequent 'seq_putc()' should also be removed, because the commit that caused all these problems already added the final '\n' to the seq_printf() above it.

Commit 660c486590aa ("PCI: dwc: Set 32-bit DMA mask for MSI target address allocation") added dma_mask_set() call to explicitly set 32-bit DMA mask for MSI message mapping, but for now it throws a warning on ret == 0, while dma_set_mask() returns 0 in case of success. Fix this by inverting the condition.

Device 3380 (rev ab) 0005:03:00.0 USB controller: PLX Technology, Inc. Device 3380 (rev ab) The problem seems to be dw_pcie_setup_rc() is now called twice before and after the link up handling. 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.

2020-12-26drm/amd/display: avoid uninitialized variable warningLinus Torvalds1-1/+1
clang (quite rightly) complains fairly loudly about the newly added mpc1_get_mpc_out_mux() function returning an uninitialized value if the 'opp_id' checks don't pass. This may not happen in practice, but the code really shouldn't return garbage if the sanity checks don't pass. So just initialize 'val' to zero to avoid the issue.
