 The bitbanger routine in this driver (lm70_txrx) is called back from
 the bound "hwmon/lm70" protocol driver through its sysfs hook, using a
 spi_write_then_read() call.  It performs Mode 0 (SPI/Microwire) bitbanging.
-The lm70 driver then inteprets the resulting digital temperature value
+The lm70 driver then interprets the resulting digital temperature value
 and exports it through sysfs.

  - CPHA indicates the clock phase used to sample data; CPHA=0 says
    sample on the leading edge, CPHA=1 means the trailing edge.
 
-   Since the signal needs to stablize before it's sampled, CPHA=0
+   Since the signal needs to stabilize before it's sampled, CPHA=0
    implies that its data is written half a clock before the first
    clock edge.  The chipselect may have made it become available.
