drivers/atm/idt77252.c: Remove unnecessary error check
This code does not call deinit_card(card); in an error case, as done in
other error-handling code in the same function. But actually, the called
function init_sram can only return 0, so there is no need for the error
check at all.
init_sram is also given a void return type, and its single return statement
at the end of the function is dropped.
A simplified version of the sematic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@r exists@
@r@
statement S1,S2,S3;
constant C1,C2,C3;
@@
*if (...)
{... S1 return -C1;}
...
*if (...)
{... when != S1
return -C2;}
...
*if (...)
{... S1 return -C3;}
// </smpl>
