linux-toradex.git/drivers/gpu/drm/tilcdc, branch v3.10.78 Linux kernel for Apalis and Colibri modules drm/tilcdc: Fix the error path in tilcdc_load() 2014-11-14T16:47:56+00:00 Ezequiel Garcia ezequiel@vanguardiasur.com.ar 2014-09-02T12:51:15+00:00 a3cb445501d51791746af4066e480650d85d2f97 commit b478e336b3e75505707a11e78ef8b964ef0a03af upstream. The current error path calls tilcdc_unload() in case of an error to release the resources. However, this is wrong because not all resources have been allocated by the time an error occurs in tilcdc_load(). To fix it, this commit adds proper labels to bail out at the different stages in the load function, and release only the resources actually allocated.

commit b478e336b3e75505707a11e78ef8b964ef0a03af upstream.

The current error path calls tilcdc_unload() in case of an error to release
the resources. However, this is wrong because not all resources have been
allocated by the time an error occurs in tilcdc_load().

To fix it, this commit adds proper labels to bail out at the different
stages in the load function, and release only the resources actually allocated.

Pull drm updates from Dave Airlie:
 "This is the main drm pull request for 3.10.

  Wierd bits:
   - OMAP drm changes required OMAP dss changes, in drivers/video, so I
     took them in here.
   - one more fbcon fix for font handover
   - VT switch avoidance in pm code
   - scatterlist helpers for gpu drivers - have acks from akpm

  Highlights:
   - qxl kms driver - driver for the spice qxl virtual GPU

  Nouveau:
   - fermi/kepler VRAM compression
   - GK110/nvf0 modesetting support.

  Tegra:
   - host1x core merged with 2D engine support

  i915:
   - vt switchless resume
   - more valleyview support
   - vblank fixes
   - modesetting pipe config rework

  radeon:
   - UVD engine support
   - SI chip tiling support
   - GPU registers initialisation from golden values.

  exynos:
   - device tree changes
   - fimc block support

  Otherwise:
   - bunches of fixes all over the place."

drm/tilcdc: use only a single module device table 2013-04-26T00:18:46+00:00 Arnd Bergmann arnd@arndb.de 2013-04-23T16:30:43+00:00 a59e1ff3b83726f581ba7a421af97bd1589d9e2c The tilcdc driver fails to be built as a module because of extraneous MODULE_DEVICE_TABLE entries: drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_panel.o:(.data+0x54): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here drivers/gpu/drm/tilcdc/tilcdc_drv.o:(.data+0x184): multiple definition of `__mod_of_device_table' drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here Since the entire point of these entries is to make the module autoload when one of the devices is present, it's enough to keep the one entry for "ti,am33xx-tilcdc", which should always be there if any of the others are.

The tilcdc driver fails to be built as a module because of extraneous
MODULE_DEVICE_TABLE entries:

drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of `__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here
drivers/gpu/drm/tilcdc/tilcdc_panel.o:(.data+0x54): multiple definition of `__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here
drivers/gpu/drm/tilcdc/tilcdc_drv.o:(.data+0x184): multiple definition of `__mod_of_device_table'
drivers/gpu/drm/tilcdc/tilcdc_tfp410.o:(.data+0x54): first defined here

Since the entire point of these entries is to make the module autoload
when one of the devices is present, it's enough to keep the one entry
for "ti,am33xx-tilcdc", which should always be there if any of the
others are.
