Change-Id: Ibeb4d8c4c0e8188a48d468907dc42adce40be136
mmc: sdhci-msm: set core in proper mode before reset

During probe disable the HC mode since the reset is done in
SDCC mode. HC mode will get set after the reset is complete
before the rest of the initialization is done.

msm: kgsl: Fix several possible problem spots in the dispatcher

Fix a few spots that the compiler warnings missed. Avoid
dereferencing a pointer that may have returned ERR_PTR() without
first checking to see that if it did return ERR_PTR() and correct
an egregious signed / unsigned mixup. Not sure why the compiler
didn't yell at me for that one.
