Subject: spi: mpc8xxx: Rename variable
X-Git-Tag: v2025.01-rc5-pxa1908~2937^2~6
X-Git-Url: http://git.dujemihanovic.xyz/html/static/gitweb.css?a=commitdiff_plain;h=5ccfb8a9957d1ca67082b80b27d4c9c10fc13ae0;p=u-boot.git

spi: mpc8xxx: Rename variable

The variable "char_size" holds the number of bits to be transferred in
the current loop iteration. A better name would be "xfer_bitlen", which
we rename this variable to.
