mtd: devices: fix mchp23k256 read and write
commit 14f89e088155314d311e4d4dd9f2b4ccaeef92b2 upstream.
Due to the use of sizeof(), command size set for the spi transfer
was wrong. Driver was sending and receiving always 1 byte less
and especially on write, it was hanging.
echo -n -e "\\x1\\x2\\x3\\x4" > /dev/mtd1
And read part too now works as expected.
hexdump -C -n16 /dev/mtd1
