Subject: staging/dgap: Use strpbrk() instead of dgap_sindex()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b9f7f1d0846f15585b8af64435b6b706b25a5c0b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

staging/dgap: Use strpbrk() instead of dgap_sindex()

The <linux/string.h> provides strpbrk() function that does
the same that the dgap_sindex(). Let's use already defined
function instead of writing custom.
