[Abdelnasser Hussein]

Changes in v4:
- Separated changes into two logical patches.
- Patch 1: Used guard(mutex) and devm_mutex_init() instead of manual lock/unlock and mutex_init().
- Patch 2: Used __aligned(IIO_DMA_MINALIGN) instead of ____cacheline_aligned.
- Patch 2: Fixed the sizeof() argument in spi_read().
