      由 Daniel Abrecht 提交于 
      This will make sure applications which use the IN_FORMATS blob
to figure out which modifiers they can use will pick up the
linear modifier which is needed by mxsfb. Such applications
will not work otherwise if an incompatible implicit modifier
ends up being selected.

helper took care of this.

      drm/vgem: replace idr_init() by idr_init_base() · 05854d48
      由 Deepak R Varma 提交于 
      idr_init() uses base 0 which is an invalid identifier. The new function
idr_init_base allows IDR to set the ID lookup from base 1. This avoids
all lookups that otherwise starts from 0 since 0 is always unused.

      drm/omap: Fix runtime PM imbalance on error · a5d704d3
      由 Dinghao Liu 提交于 
      pm_runtime_get_sync() increments the runtime PM usage counter
even when it returns an error code. However, users of its
direct wrappers in omapdrm assume that PM usage counter will
not change on error. Thus a pairing decrement is needed on
the error handling path for these wrappers to keep the counter
balanced.

Deterministic algorithm:
For each file:

      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions

      drm: Use state helper instead of CRTC state pointer · 253f28b6
      由 Maxime Ripard 提交于 
      Many drivers reference the crtc->pointer in order to get the current CRTC
state in their atomic_begin or atomic_flush hooks, which would be the new
CRTC state in the global atomic state since _swap_state happened when those
hooks are run.

Use the drm_atomic_get_new_crtc_state helper to get that state to make it
more obvious.

This was made using the coccinelle script below:

      由 Thomas Zimmermann 提交于 
      Fixes a build failure with msm.

This change was supposed to be part of commit 49a3f51d ("drm/gem:

      drm/fb_helper: Use min_t() to handle size_t and unsigned long · a3230bd7

Indeed, on 32-bit size_t is "unsigned int", not "unsigned long".
