2021-01-14mtd: rawnand: intel: check the mtd name only after setting the variableMartin Blumenstingl
Move the check for mtd->name after the mtd variable has actually been initialized. While here, also drop the NULL assignment to the mtd variable as it's overwritten later on anyways and the NULL value is never read.

I thought this driver was not impacted by the recent changes around the ECC engines DT parsing logic but in fact it is.

2021-01-14drm/sun4i: tcon: fix inverted DCLK polarityGiulio Benetti
During commit 88bc4178568b ("drm: Use new DRM_BUS_FLAG_*_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags") DRM_BUS_FLAG_* macros have been changed to avoid ambiguity but just because of this ambiguity previous DRM_BUS_FLAG_PIXDATA_(POS/NEG)EDGE were used meaning _SAMPLE_ not _DRIVE_. This leads to DLCK inversion and need to fix but instead of swapping phase values, let's adopt an easier approach Maxime suggested: It turned out that bit 26 of SUN4I_TCON0_IO_POL_REG is dedicated to invert DCLK polarity and this makes things really easier than before. So let's handle DCLK polarity by adding SUN4I_TCON0_IO_POL_DCLK_DRIVE_NEGEDGE as bit 26 and activating according to bus_flags the same way it is done for all the other signals polarity.

2021-01-14USB: gadget: dummy-hcd: Fix errors in port-reset handlingAlan Stern
Commit c318840fb2a4 ("USB: Gadget: dummy-hcd: Fix shift-out-of-bounds bug") messed up the way dummy-hcd handles requests to turn on the RESET port feature (I didn't notice that the original switch case ended with a fallthrough). The call to set_link_state() was inadvertently removed, as was the code to set the USB_PORT_STAT_RESET flag when the speed is USB2. In addition, the original code never checked whether the port was connected before handling the port-reset request. There was a check for the port being powered, but it was removed by that commit! In practice this doesn't matter much because the kernel doesn't try to reset disconnected ports, but it's still bad form. This patch fixes these problems by changing the fallthrough to break, adding back in the missing set_link_state() call, setting the port-reset status flag, adding a port-is-connected test, and removing a redundant assignment statement.

2021-01-14drm/i915/pps: abstract panel power sequencer from intel_dp.cJani Nikula
In a long overdue refactoring, split out all panel sequencer code from intel_dp.c to new intel_pps.[ch]. The first part is mostly just code movement as-is, without cleanups or functional changes. We need to add a vlv_get_dpll() helper to get at the vlv/chv dpll from pps code. v2: Rebase.

2021-01-14drm/amdkfd: Fix out-of-bounds read in kdf_create_vcrat_image_cpu()Jeremy Cline
KASAN reported a slab-out-of-bounds read of size 1 in kdf_create_vcrat_image_cpu(). This occurs when, for example, when on an x86_64 with a single NUMA node because kfd_fill_iolink_info_for_cpu() is a no-op, but afterwards the sub_type_hdr->length, which is out-of-bounds, is read and multiplied by entries. Fortunately, entries is 0 in this case so the overall crat_table->length is still correct. Check if there were any entries before de-referencing sub_type_hdr which may be pointing to out-of-bounds memory.

2021-01-14Revert "drm/amd/display: Fixed Intermittent blue screen on OLED panel"Rodrigo Siqueira
commit a861736dae64 ("drm/amd/display: Fixed Intermittent blue screen on OLED panel") causes power regression for many users. It seems that this change causes the MCLK to get forced high; this creates a regression for many users since their devices were not able to drop to a low state after this change. For this reason, this reverts commit a861736dae644a0d7abbca0c638ae6aad28feeb8.

2021-01-14drm/amd/display: disable dcn10 pipe split by defaultLi, Roman
[Why] The initial purpose of dcn10 pipe split is to support some high bandwidth mode which requires dispclk greater than max dispclk. By initial bring up power measurement data, it showed power consumption is less with pipe split for dcn block. This could be reason for enable pipe split by default. By battery life measurement of some Chromebooks, result shows battery life is longer with pipe split disabled. [How] Disable pipe split by default. Pipe split could be still enabled when required dispclk is greater than max dispclk.
