Subject: drivers/base/core.c: use strreplace()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a29fd614a6af57610b1963e3445f1758c3806187;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

drivers/base/core.c: use strreplace()

This eliminates a little .text and avoids repeating the strchr call when
we meet a '!' (which will happen at least once).
