Duoming Zhou 0801c893fd clk: zynq: Prevent null pointer dereference caused by kmalloc failure ... [ Upstream commit 7938e9ce39 ] The kmalloc() in zynq_clk_setup() will return null if the physical memory has run out. As a result, if we use snprintf() to write data to the null address, the null pointer dereference bug will happen. This patch uses a stack variable to replace the kmalloc().
