Subject: mtd: dataflash: Get rid of loop counter in jedec_probe()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a296a1bc3eb54382d2a61d47529e71c9d3bc615e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mtd: dataflash: Get rid of loop counter in jedec_probe()

"For" loop in jedec_probe can be simplified to not need counter
'i'. Convert the code and get rid of the variable.
