scripts: kernel-doc: fix array element capture in pointer-to-func par…
…sing Currently, kernel-doc causes an unexpected error when array element (i.e., "type (*foo[bar])(args)") is present as pointer parameter in pointer-to-function parsing. For e.g., running kernel-doc -none on kernel/gcov/gcc_4_7.c causes this error: "Use of uninitialized value $param in regexp compilation at ...", in combination with: "warning: Function parameter or member '' not described in 'gcov_info'" Here, the parameter parsing does not take into account the presence of array element (i.e. square brackets) in $param. Provide a simple fix by adding square brackets in the regex, responsible for capturing $param. A quick evaluation, by running 'kernel-doc -none' on entire kernel-tree, reveals that no additional warning or error has been added or removed by the fix.
