Subject: msm: camera: Fix possible out of bound writes in csi driver
|
|
|
|
The value csi_lane_mask which is uint16_t is controllable from userspace.
|
|
The while loop can loop for 2^16 - 1, Hence extract the required
|
|
bit combination from the userspace argument, used it for further
|
|
processing.
