Geert Uytterhoeven 0278b34bf1 spi: spidev_test: Fix buffer overflow in unescape() ... Sometimes spidev_test crashes with: *** Error in `spidev_test': munmap_chunk(): invalid pointer: 0x00022020 *** Aborted or just Segmentation fault This is due to transfer_escaped_string() miscalculating the required size of the buffer by one byte, causing a buffer overflow in unescape(). Drop the bogus "+ 1" in the strlen() parameter to fix this. Note that unescape() never copies the zero-terminator of the source string, so it writes at most as many bytes as the length of the source string.
