2021-01-13phy: stm32: rework PLL Lock detectionAmelie Delaunay
USBPHYC has a register per phy to control and monitor the debug interface of the HS PHY through a digital debug access. With this register, it is possible to know if PLL Lock input to phy is high. That means the PLL is ready for HS operation. Instead of using an hard-coded delay after PLL enable and PLL disable, use this bit to ensure good operating of the HS PHY. Also use an atomic counter (n_pll_cons) to count the actual number of PLL consumers and get rid of stm32_usbphyc_has_one_phy_active. The boolean active in the usbphyc_phy structure is kept, because we need to know in remove if a phy_exit is required to properly disable the PLL.

2020-12-27proc mountinfo: make splice available againLinus Torvalds
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.

2020-12-26mfd: ab8500-debugfs: Remove extraneous seq_putcLinus Torvalds
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.

2020-12-25PCI: dwc: Fix inverted condition of DMA mask setup warningAlexander Lobakin
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.
