From 3894817fb1df6261bbfff7d2d540510372883543 Mon Sep 17 00:00:00 2001 From: Himangi Saraogi Date: Sun, 20 Jul 2014 03:19:59 +0530 Subject: powerpc/fsl-pci: Correct use of ! and & In commit ae91d60ba88ef0bdb1b5e9b2363bd52fc45d2af7, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The Coccinelle semantic patch that makes this change is as follows: // @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // Signed-off-by: Himangi Saraogi Signed-off-by: Scott Wood --- arch/powerpc/sysdev/fsl_pci.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/powerpc/sysdev/fsl_pci.c') diff --git a/arch/powerpc/sysdev/fsl_pci.c b/arch/powerpc/sysdev/fsl_pci.c index 4bd091a05583..c5077673bd94 100644 --- a/arch/powerpc/sysdev/fsl_pci.c +++ b/arch/powerpc/sysdev/fsl_pci.c @@ -853,8 +853,8 @@ u64 fsl_pci_immrbar_base(struct pci_controller *hose) in = pcie->cfg_type0 + PEX_RC_INWIN_BASE; for (i = 0; i < 4; i++) { /* not enabled, skip */ - if (!in_le32(&in[i].ar) & PEX_RCIWARn_EN) - continue; + if (!(in_le32(&in[i].ar) & PEX_RCIWARn_EN)) + continue; if (get_immrbase() == in_le32(&in[i].tar)) return (u64)in_le32(&in[i].barh) << 32 | -- cgit v1.2.3
