Subject: staging: rtl8723bs: use PTR_ALIGN for buffer alignment
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=69dc48dc550640b1c33e30f32620fe5ef1b068e9;p=thirdparty%2Fkernel%2Flinux.git

staging: rtl8723bs: use PTR_ALIGN for buffer alignment

Replace manual pointer alignment calculation with the standard PTR_ALIGN
macro in rtw_init_cmd_priv()

This improves code readability and ensures the use of kernel's
preferred alignment mechanism instead of manual calculation
