[ Upstream commit82a0a3e6f8] My static checker rule complains about this code. The concern is that if "sample_space" is negative then the "sample_space >= runtime->channels" condition will not work as intended because it will be type promoted to a high unsigned int value. strm->fifo_sample_size is SSI_FIFO_DEPTH (32). The SSIFSR_TDC_MASK is 0x3f. Without any further context it does seem like a reasonable warning and it can't hurt to add a check for negatives.
