Input: maplemouse - fix NULL pointer dereference in open() Commit 555c765b0cc2 ("Input: mouse - drop unnecessary calls to input_set_drvdata") dropped the input_set_drvdata() call in probe because the data appeared to be unused. However, dc_mouse_open() and dc_mouse_close() were using maple_get_drvdata(to_maple_dev(&dev->dev)). This appears to be accessing the data attached to an instance of maple_device structure, while in reality this actually retrieves driver data from the input device's embedded struct device (doing invalid conversion of input device structure to maple device). After input_set_drvdata() was removed, that lookup started returning NULL and opening the input device dereferences mse->mdev. Restore input_set_drvdata() and convert open() and close() to use input_get_drvdata() so the dependency is no longer hidden.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
