Hi all,

After merging the spi tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

drivers/spi/spi-ti-qspi.c: In function 'ti_qspi_start_transfer_one':
drivers/spi/spi-ti-qspi.c:392:8: warning: 'rx_wlen' may be used uninitializ=
ed in this function [-Wmaybe-uninitialized]
  392 |     if (rx_wlen >=3D 32)
      |        ^
drivers/spi/spi-ti-qspi.c:318:12: note: 'rx_wlen' was declared here
  318 |  u8 rxlen, rx_wlen;
      |            ^~~~~~~

Introduced by commit

  e7cc5cfbea4c ("spi: spi-ti-qspi: optimize byte-transfers")

Looks like it may be a false positive.

Cheers,
Stephen Rothwell
