teres1-audioselect: check for read > 0, loop and cosmetic

[khumarahn]

Hi,

I made changes similar to those in teres1-ledctrl.

I removed installation of systemd service files from Makefile. I think they need to be handled separately. My system does not even have systemd.

Thank you for the feedback! I re-wrote this service, and included your suggestions. You can see it here: https://github.com/d3v1c3nv11/teres1-audioselect
It needs few days of testing before merging to master branch. You can test it too in gentoo and tell me if it is alright. Thank you again for the contribution.

ok, thanks. I should be able to look at it later closely. Now, there is some compilation error:

$ make
cc teres1-audioselect.c -o teres1-audioselect
teres1-audioselect.c: In function ‘main’:
teres1-audioselect.c:84:5: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘off_t’
     off_t offset = SUNXI_HMIC_STS;
     ^
teres1-audioselect.c:125:19: error: ‘ie’ undeclared (first use in this function)
   while(read(fd, &ie, sizeof(struct input_event))>0)
                   ^
teres1-audioselect.c:125:19: note: each undeclared identifier is reported only once for each function it appears in
make: *** [Makefile:2: all] Error 1

also, if you could use some consistent indentation, this would really help
