Change 2ef4fb92363c ("drm/vmwgfx: Make sure bo's are unpinned before putting them back") caused a conflict in one of the drm trees and the merge commit 68a32ba14177 ("Merge tag 'drm-next-2021-04-28' of git://anongit.freedesktop.org/drm/drm") accidently re-added code that the original change was removing. Fixed by removing the incorrect buffer unpin - it has already been unpinned two lines above.

2021-07-09drm/i915: Add release id versionLucas De Marchi3-2/+18
Besides the arch version returned by GRAPHICS_VER(), new platforms contain a "release id" to make clear the difference from one platform to another. The release id number is not formally defined by hardware until future platforms that will expose it via a new GMD_ID register. For the platforms we support before that register becomes available we will set the values in software and we can set them as we please. So the plan is to set them so we can group different features under a single GRAPHICS_VER_FULL() check. After GMD_ID is used, the usefulness of a "full version check" will be greatly reduced and will be mostly used for deciding workarounds and a few code paths. So it makes sense to keep it as a separate field from graphics_ver. Also, as a platform with `release == n` may be closer feature-wise to `n - 2` than to `n - 1`, use the word "release" rather than the more common "minor" for this This is a mix of 2 independent changes: one by me and the other by Matt Roper. v2: - Reword commit message to make it clearer why we don't call it "minor" (Matt Roper and Tvrtko) - Rename variables s/*_ver_release/*_rel/ and print them in a single line formatted as {ver}.{rel:2} (Jani and Matt Roper) Cc: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210707235921.2416911-2-lucas.demarchi@intel.com

2021-07-09drm/panel: add basic DP AUX backlight supportRajeev Nandan1-0/+108
Some panels support backlight control over DP AUX channel using VESA's standard backlight control interface. Using new DRM eDP backlight helpers, add support to create and register a backlight for those panels in drm_panel to simplify the panel drivers. The panel driver with access to "struct drm_dp_aux" can create and register a backlight device using following code snippet in its probe() function: err = drm_panel_dp_aux_backlight(panel, aux); if (err) return err; Then drm_panel will handle backlight_(enable|disable) calls similar to the case when drm_panel_of_backlight() is used. Currently, we are not supporting one feature where the source device can combine the backlight brightness levels set through DP AUX and the BL_PWM_DIM eDP connector pin. Since it's not required for the basic backlight controls, it can be added later.

2021-07-09irqchip/mips: Fix RCU violation when using irqdomain lookup on interrupt entryMarc Zyngier3-11/+12
Since d4a45c68dc81 ("irqdomain: Protect the linear revmap with RCU"), any irqdomain lookup requires the RCU read lock to be held. This assumes that the architecture code will be structured such as irq_enter() will be called *before* the interrupt is looked up in the irq domain. However, this isn't the case for MIPS, and a number of drivers are structured to do it the other way around when handling an interrupt in their root irqchip (secondary irqchips are OK by construction). This results in a RCU splat on a lockdep-enabled kernel when the kernel takes an interrupt from idle, as reported by Guenter Roeck. Note that this could have fired previously if any driver had used tree-based irqdomain, which always had the RCU requirement. To solve this, provide a MIPS-specific helper (do_domain_IRQ()) as the pendent of do_IRQ() that will do thing in the right order (and maybe save some cycles in the process). Ideally, MIPS would be moved over to using handle_domain_irq(), but that's much more ambitious.

2021-07-08cxgb4: fix IRQ free race during driver unloadShahjada Abul Husain2-8/+13
IRQs are requested during driver's ndo_open() and then later freed up in disable_interrupts() during driver unload. A race exists where driver can set the CXGB4_FULL_INIT_DONE flag in ndo_open() after the disable_interrupts() in driver unload path checks it, and hence misses calling free_irq(). Fix by unregistering netdevice first and sync with driver's ndo_open(). This ensures disable_interrupts() checks the flag correctly and frees up the IRQs properly.

2021-07-08drm/amdgpu: Fix signedness bug in __amdgpu_eeprom_xfer()Dan Carpenter1-1/+1
The i2c_transfer() function returns negatives or else the number of messages transferred. This code does not work because ARRAY_SIZE() is type size_t and so that means negative values of "r" are type promoted to high positive values which are greater than the ARRAY_SIZE(). Fix this by changing the < to != which works regardless of type promotion.
