Subject: staging: rtl8192u: remove unused functions in r8192U_core.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=af8b19c4a8ed156904e14d97dd186f5d8858acd6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: rtl8192u: remove unused functions in r8192U_core.c

We get 2 warnings when building kernel with W=1:
drivers/staging/rtl8192u/r8192U_core.c:925:12: warning: no previous declaration for 'ieeerate2rtlrate' [-Wmissing-declarations]
drivers/staging/rtl8192u/r8192U_core.c:958:12: warning: no previous declaration for 'rtl8192_rate2rate' [-Wmissing-declarations]
drivers/staging/rtl8192u/r8192U_core.c:1322:11: warning: no previous declaration for 'rtl8192_IsWirelessBMode' [-Wmissing-declarations]

In fact, these functions are unused in
r8192U_core.c, but should be removed.

So this patch removes the unused functions.
