Subject: [PATCH 0/2] i2c: qup: Fixed the DMA transfer errors

These patches contain the I2C QUP (Qualcomm Universal Peripheral) DMA
related fixes. The first patch cleared the error bits in ISR, which
resolves the kernel hang for I2C bus errors and DMA transfer. The
second patch fixed the DMA segments length, which resolves the issue
for I2C transfer failure over 255 bytes.
