Subject: regmap: debugfs: "registers" & "access" for single register maps
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=676970da5cf6fec096945a8bbc19749089af57aa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

regmap: debugfs: "registers" & "access" for single register maps

When a map covers a single register, max_register is equal
to 0, so the "registers" & "access" files were not created.
Now they will be, as register 0 must be readable for such
map to make sense.
