Subject: [PATCH 00/12] staging: some memory-related patches

From: Xiaoke Wang <xkernel.wang@...mail.com>

This is a collection about some memory-related bugs fixing.
In brief, there are two types about them.
First is some memory allocation functions are called without proper
checking, which may result in wrong memory access in the subsequent
running or some else.
Second is lacking proper error handling that does not release some
allocated resources, which may result in memory leak problems.

These issuses are similar, so they are put in this series together.
Note that most of them are sent as each separate patch before, this series
rebased them to the lasted version. While there are some inherent logical
relationships between 03~05/11~12.
