Subject: i2c: qup: use address helper function in read transfer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0130944bc1d212ad4b33584424d56fe7c049eb65;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

i2c: qup: use address helper function in read transfer

qup_i2c_issue_read() derives the address from i2c_msg.
This called in the read path when I2C_M_RD flag is set.
Therefore, use the 8 bit address helper function.
