[Qemu-devel] [PATCH v2] es1370: Fix compiler warnings for debug code

[Stefan Weil <weil@mail.berlios.de>]

The patch fixes these gcc warnings:

./hw/es1370.c: In function ‘es1370_update_voices’:
./hw/es1370.c:411: error: format ‘%d’ expects type ‘int’, but argument 3 has type ‘size_t’
./hw/es1370.c: In function ‘es1370_writel’:
./hw/es1370.c:579: error: format ‘%d’ expects type ‘int’, but argument 3 has type ‘long int’
./hw/es1370.c:589: error: format ‘%d’ expects type ‘int’, but argument 3 has type ‘long int’
./hw/es1370.c:606: error: format ‘%d’ expects type ‘int’, but argument 3 has type ‘long int’
./hw/es1370.c: In function ‘es1370_readl’:
./hw/es1370.c:748: error: suggest braces around empty body in an ‘if’ statement

v2

* Use %zd for pointer differences (ptrdiff_t or ssize_t).
  The gcc error message ("long int") was misleading.
  Malc, thank you for this hint.
