Homogenize "__asm__ volatile" vs "asm volatile"

Browse Source 
According to https://gcc.gnu.org/onlinedocs/gcc/extensions-to-the-c-language-family/how-to-use-inline-assembly-language-in-c-code.html

For the C language, the asm keyword is a GNU extension. When
writing C code that can be compiled with -ansi and the -std options
that select C dialects without GNU extensions, use __asm__ instead
of asm (see Alternate Keywords). For the C++ language, asm is a
standard keyword, but __asm__ can be used for code compiled with
-fno-asm.
