Subject: spi: spi-qpic-snand: remove 'qpic_snand_op' structure
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f73dc37ebf45573349aee0aae168e8dc3d13ecee;p=users%2Fjedix%2Flinux-maple.git

spi: spi-qpic-snand: remove 'qpic_snand_op' structure

The 'qpic_snand_op' structure is used only in the qcom_spi_send_cmdaddr()
function as a type of a local variable. Additionally, the sole purpose of
that variable is to keep some interim values before those gets passed as
arguments for cpu_to_le32() calls.

In order to simplify the code, remove the definition of the structure
along with the local variable, and use the corresponding values directly
as parameters for cpu_to_le32() calls.

No functional changes intended.
