The ASLR'd codebin base(rtld+0) for the below addrs is 0x6f0c00000. For "prev ver" it's 0x5381800000.

 L_6f0c26f84
 new func.
 called via vtable funcptr.
 return L_6f0c2814c(inx0+8, inx1, w2=0xd9) & 0xffffffff;
 
 L_6f0c2814c
 inx0=_this inx1=0x40-byte outbuf copied from cmdreply inw2=cmdid
 new func.
 Sends an ipc cmd, service unknown.
 only called by L_6f0c26f84.
 
 L_6f0c373f4
 updated, prev ver @ L_5381837284.
 For the func call executed from the first branch(L_6f0c377e8()), x1 and x2 are now set: x1 = *(0x6f0d9d000+0xfc0)+0x90, x2 = 0x6f0d44000+0xb36("ncm")
 
 L_6f0c377e8
 updated, prev ver @ L_5381837640.
 Basically, instead of hard-coded inputs for various stuff, code now loads those using the additional input params.
 
 L_6f0c378b4
 updated, prev ver @ L_538183771c.
 ipc related func.
 After the first func call, instead of "if(inx0==0 || ret^1)return;" this now just does "if(ret==0)return;" and "objptr = *(inx0+32);" afterwards.
 The code at the end was replaced with code for calling a vtable funcptr from the objptr.
 
 L_6f0c379fc
 updated, prev ver @ L_5381837874.
 Instead of writing 0 to sp8, this now writes *(inx0+32) there.
 
 L_6f0c37a94
 updated, prev ver @ L_5381837904.
 Same change as L_6f0c379fc.
 
 L_6f0c37bf8

 updated, prev ver @ L_5381851d2c.
 w7 passed to L_6f0c3a83c() with both calls is now value 7 instead of 0.
 This also now calls L_6f0c3af70() when the retval from the previous func-call is zero.
